"According to Däniken, one Chi Pu Tei (Chinese:齊福泰), a professor of archeology at Beijing University, in 1938 was on an expedition with his students to explore a series of caves in the Bayan Kara Ula range of the Himalayan mountains, near Qinghai region. Däniken claims that the caves appeared to have been artificially carved into a system of tunnels and underground storerooms, with walls that were squared and glazed, as if cut into the mountain with great heat.
The explorers are said by Däniken to have found many neat rows of tombs with short 138 cm skeletons buried within. The skeletons had abnormally big heads, and small, thin, fragile bodies. A member of the team suggested that these might be the remains of an unknown species of mountain gorilla. Prof. Chi Pu Tei was said to respond, "Who ever heard of apes burying one another?"
There were no epitaphs at the graves, but instead hundreds of 30 cm wide stone discs - referred to as Dropa Stones - each with a 20 mm hole in their centers. Each stone disk was said to be inscribed with two fine grooves spiraling from the edge to a hole in the disk's center, resembling the Phaistos Disk. The disks were labeled along with other finds of the expedition and stored away at Beijing University for 20 years, during which deciphering attempts were unsuccessful.
Däniken further claims that the disks were closely examined by one Dr. Tsum Um Nui of Beijing around 1958, who concluded that each groove actually consisted of a series of tiny hieroglyphs of unknown pattern and origin. The rows of hieroglyphs were so small that a magnifying glass was needed to see them clearly. Many of the hieroglyphics had been worn away by erosion. When Dr. Tsum somehow deciphered the symbols, they told the story of the crash-landing of the Dropa spaceship and the killing of most of the survivors by local people.
According to Däniken, one of the lines of the hieroglyphs reads,
"The Dropas came down from the clouds in their aircraft. Our men, women and children hid in the caves ten times before sunrise. When at last they understood the sign language of the Dropas, they realized that the newcomers had peaceful intentions…"
Another section expresses "regret" by the Ham that the aliens' craft had crash-landed in such a remote and inaccessible mountain range and that there had been no way to build a new one to enable the Dropas to return to their own planet.
"Tsum Um Nui" is not a real Chinese name and it has been suggested it was either fictitious or was a Japanese name that was transliterated into Chinese, though the syllable "Um" is not phonologically possible in the Japanese language."

I have been researching these for quite sometime, but every trail I've found has turned up cold.
