"A total of 131 hanging coffins were recently discovered in Moping township of Zigui county, central China's Hubei province. The coffins were found on a cliff that was 50 meters wide and 100 meters high." Source: Archaeology News Network (2015).
"It is one of the biggest hanging coffin tomb sites to be found so far in Chinese mainland. The wooden coffins were placed in man-made caves or natural rock tunnels on the cliff. According to archaeologists, these hanging coffin tombs can be traced back to the Tang Dynasty of 1,200 years ago, and the tomb owners were Bo people, an ancient aboriginal tribe in southwest China."

"Hanging coffins are an ancient funeral custom of some ethnic groups, especially the Bo people of southern China. Coffins of various shapes were mostly carved from one whole piece of wood. Hanging coffins either lie on beams projecting outward from vertical faces such as mountains, are placed in caves in the face of cliffs, or sit on natural rock projections on mountain faces." Source: Wikipedia.
"It was said that the hanging coffins could prevent bodies from being taken by beasts and also bless the soul eternally. Spiritually, the Bo people viewed the mountain cliffs as a stairway to heaven and believed that by placing the coffins up high the deceased would be closer to heaven. A practical reason for placing the coffins on cliffs includes isolation, so that they are hard for animals to reach and less vulnerable to destruction."
Notes: "The Belitung shipwreck (also called the Tang shipwreck or Batu Hitam shipwreck) is the wreck of an Arabian dhow which sailed a route from Africa to China around 830 AD. The ship completed the outward journey, but sank on the return journey, approximately 1 mile (1.6 km) off the coast of Belitung Island, Indonesia." Source: Wikipedia.
The Belitung shipwreck, along with two other ships discovered in the area, "turned out to be an undersea treasure trove of such massive historical significance that Shanghai, Singapore and Doha in Qatar are vying with each other to buy the cargo," according to The Independent (2011) .
"The treasure was part of a huge cargo of eighth-century porcelain that traders from the Chinese Tang dynasty had put aboard an Arab dhow for export to Malaysia, India and what is now Saudi Arabia. The dhow's remains, found among the treasure, suggest the ship was wrecked on the treacherous underwater reefs of Indonesia's Karimata straits on its outward voyage through the Java sea."

Comment: This theory is speculative, but the idea that Roman soldiers ended up in China isn't totally implausible. The general scenario of how it could have happened goes like this:
In 53 BC, the Roman politician and general Marcus Crassus (115-53 BC) was killed at the Battle of Carrhae when he led his army into a trap during his ill-advised invasion of Parthia, an empire which bordered on China:
This map shows the location of Parthia when it was part of the Median Empire around 600 BC. Parthia is in the upper part of the yellow region just to the right of the Caspian Sea.
Crassus' invasion of Parthia was a complete disaster:
"In a slaughter known as the battle of Carrhae the Romans lost nearly their entire army and Crassus was killed. [The story is that the Parthians captured Crassus, the richest man in Rome, and executed him by pouring molten gold down his throat.] The remaining 10,000 or so Roman legionaries were captured." Source: War History Online.
The Parthians apparently used their Roman prisoners as border guards along the eastern frontiers:
"The Parthians had a standard practice of employing captured soldiers as border guards. By transferring the 10,000 legionaries to the eastern borders they prevented any realistic chance of escape for the Romans who likely would have simply accepted their new lot in life. Record of the soldiers vanish for about 17 years when the battle of Zhizhi was fought as a Chinese army under Chen Tang assaulted a border town known today as Taraz, located in Kazakhstan near the border of Kyrgyzstan." (War History Online)
According to the story, some of these former Roman soldiers and Parthian border guards fought as mercenaries at the battle of Zhizhi. They were either captured or defected to the Chinese, who were impressed by their fighting abilities and -- like the Parthians -- stationed them in a border town to guard the frontier:
"Anywhere from 100 to 1,000 or more soldiers established themselves in this town that was known by the Chinese as Liqian/Li-Jien, which is pronounced as 'legion'." (War History Online) "...It seems these Romans lived peacefully in Liqian, and 2,000 years later we have DNA evidence that over 50% of the villagers in modern day Liqian have Caucasian ancestry including green and blue eyes, increased average height and other distinguishing characteristics such as distinctly Roman noses."
If this story is true, then these Roman soldiers who fought under Crassus at Carrhae (and their descendants) had an extremely wild and strange destiny, to say the least. But is the story true?
First of all, there's no doubt that the inhabitants of the region of Liqian, China, have some kind of European ancestry. According to Wikipedia, "The area of the former Liqian city is known for the distinctive physical appearance of its inhabitants. The population has higher frequencies of traits prevalent in Europe, such as aquiline noses, blonde or light-colored hair, blue or green eyes, and relatively fair skin tones."
Who were these Europeans and where did they come from? The idea that they were Roman soldiers or their descendants isn't all that farfetched, but it's still controversial:
"A hypothesis by the sinologist Homer H. Dubs, according to which Roman legionaries clashed with Han troops during the battle and were resettled afterwards in a Chinese village named Liqian, has been rejected by modern historians and geneticists on the grounds of a critical appraisal of the ancient sources and recent DNA testings of the village people. However, this hypothesis has been supported by prominent scholars like Lev Gumilev."
There's also a theory that the people of Liqian may be descended from some of Alexander the Great's soldiers, but it seems more likely that their ancestors were Caucasoid Indo-Europeans who lived in the region long before the Romans:
You can always trust the experts to mess up a good story, but I've got to admit that some of these Chinese do look like they have Roman ancestry. The people in Liqian are trying to use their supposed relationship with the Romans to boost their tourism industry and who can blame them? Whether the story is true or not is a different matter altogether.
"One thousand years before the first Fourth of July, the first fireworks exploded. It didn't rain twinkling stars or light up the night sky — but to the complete surprise and misfortune of one Chinese chemist, it did go 'bang.'" Source: Live Science.
"This 'bang' was the product of an ancient quest for immortality, according to Gunpowder, Explosives and the State: A History (Routledge, 2016) . In early-ninth-century China, alchemy was all the rage. The goal of alchemy was to produce a substance that would prolong life, or even cheat death. Alchemy never did uncover a death-defying concoction. But it did produce an explosion that would change the way we celebrate holidays worldwide.
Note: "Whereas European alchemy eventually centered on the transmutation of base metals into noble metals, Chinese alchemy had a more obvious connection to medicine. The philosopher's stone of European alchemists can be compared to the Grand Elixir of Immortality sought by Chinese alchemists. However, in the hermetic view, these two goals were not unconnected, and the philosopher's stone was often equated with the universal panacea; therefore, the two traditions may have had more in common than initially appears."

"... In this study, the Maijishan Grottoes, a famous Buddhist cave temple located on the ancient Silk Road in China, was selected. The Maijishan Grottoes are known for their beautiful scenery, numerous caves, precious artwork and long-spanning history. The site was added to the World Heritage List in 2014 as one of the key historical sites of the 'Silk Roads, the Route Network of the Chang'an-Tianshan Corridor.' The priceless painted sculptures that are preserved in the caves of the Maijishan Grottoes are severely threatened by multiple factors, including the poor stability of the mountain rocks, frequent earthquakes, water seepage, microclimate change and human disturbance, in addition to microorganisms."
Note: "Cave shrines in China probably served two purposes: originally, before Buddhism came to China, they may have been used as local shrines to worship one's ancestors or various nature deities. With the coming of Buddhism to China, however, influenced by the long tradition of cave shrines from India (such as Ajanta) and Central Asia (primarily Afghanistan), they became part of China's religious architecture.

"Mustang Caves or Sky Caves of Nepal are a collection of some 10,000 man-made caves dug into the sides of valleys in the Mustang District of Nepal. Several groups of archaeologists and researchers have explored these stacked caves and found partially mummified human bodies and skeletons that are at least 2,000–3,000 years old. Explorations of these caves by conservators and archaeologists have also led to the discovery of valuable Buddhist paintings, sculptures, manuscripts and numerous artifacts belonging to the 12th to 14th century. The caves lie on the steep valley walls near the Kali Gandaki River in Upper Mustang. Research groups have continued to investigate these caves, but no one has yet understood who built the caves and why were they built." Source: Wikipedia.

Note: Back in 2011, National Geographic announced that "The remains of 27 ancient men, women, and children" had been discovered in these caves. Several of the bodies had been defleshed and "many of the bones bear cut marks that point to a previously unknown Himalayan death ritual." Defleshing or excarnation "refers to the practice of removing the flesh and organs of the dead before burial, leaving only the bones." (Wikipedia)
According to Mental Floss (2016), "[s]cientists recently sequenced the whole genomes of eight individuals found in these ancient chambers, revealing the secrets of the first inhabitants of the Himalayas." The DNA analysis revealed that "the first inhabitants of the Himalayas came down from the north, from East Asian populations of the Tibetan plateau. Their genetic profile most closely resembles modern-day Sherpa and Tibetan populations."
"A 4,300-year-old city, which has a massive step pyramid that is at least 230 feet (70 meters) high and spans 59 acres (24 hectares) at its base, has been excavated in China, archaeologists reported in the August issue of the journal Antiquity." Source: Live Science.
"The remains of numerous human sacrifices have been discovered at Shimao [the name given to the city]. 'In the outer gateway of the eastern gate on the outer rampart alone, six pits containing decapitated human heads have been found,' the archaeologists wrote."
"About 2,300 years ago, the grandmother of China's first emperor received an elaborate burial outfitted with a macabre menagerie of buried animals — notably, the remains of an ancient, extinct gibbon that was previously unknown to science, a new study finds." Source: Live Science.
"The discovery is remarkable because the ape — a gibbon the scientists named Junzi imperialis — is the first ape on record to go extinct since the last ice age, the researchers said."
Note: "In 2004, archaeologists excavated the tomb attributed to Lady Xia, the grandmother of the emperor Qin Shi Huang (259 B.C. to 210 B.C.), in the Shaanxi province of central China. But the tomb contained more than Lady Xia's burial; it also included 12 pits filled with animal remains, including the skeletons of a leopard ... a Eurasian lynx ... an Asiatic black bear ... a crane ... domesticated mammals, birds and, surprisingly, a mysterious gibbon."

Comment: There's less to this story than it would appear. According to Live Science, "The archaeologists aren't sure whether or not the statues were buried at the same time as the cremated remains..." and "... did not speculate on whether any of the remains are actually from the Buddha who died around 2,500 years ago."
The archaeologists went on to note that "previous archaeological discoveries in China have also revealed human remains with inscriptions that claim that they belong to the Buddha ... These include a skull bone, supposedly from the Buddha, found inside a gold chest in Nanjing." As noted in the video, "experts" have also claimed to have found the remains of the Buddha in India.
I'm not surprised that the archaeologists who found these cremated remains refused to speculate about whether they actually belonged to Siddhartha Guatama. After all, how could they possibly know? It's not like we have DNA samples from the Buddha that could be used in the identification. The transcriptions aren't that useful, either, since so many other alleged burial sites with similar transcriptions have been found elsewhere. Some of them, at least, have to be fake, but since it's unclear whether the Buddha actually existed in the first place, it's quite possible that all of them are completely bogus.

This means that "close contact existed between the First Emperor's China and the West before the formal opening of the Silk Road," according to one Chinese archaeologist.
