I think I can speak for the Chinese Yeren, as I was the BFRO investigator in China, while I was living and working there. There have been many, many sightings, including by politicians, and the military, in China. The government has organized, I think 3, major expeditions so far. All of them have had at least a platoon of armed PLA soldiers. On one such expedition, "rounds were fired downrange", but the members were too shocked/scared to even come close to hitting their target (Yeren). It was a clear sighting, with no mistake as to what they were seeing.
I even managed an email interview with a Yeren investigator. Sort of a Chinese "Matt Moneymaker", of sorts (if you can imagine that LOL). This gentleman had a sighting many, many years ago, as a young man. It stayed with him, and his remembrances of the creature were so vivid that he eventually quit his job and took up field researching full-time. He would not bathe for 2 weeks before going out, and would spend up to 3 months in the bush of Shenongjia Nature Preserve, with a homemade black powder rifle, hoping for another encounter. He eventually did have one where the creature charged him, but since it was the rainy season, his powder was wet, and the gun wouldn't fire. The Yeren stopped about 15 feet away from him, turned, and went off into the forest.
It was an extremely interesting interview ... until he got to the point where he was praising the Party, and asking for funding and equipment from me.
The government of China DOES acknowledge the existence of a "bipedal human-like creature" in the forests of Shenongjia, but not publicly. The nearest major city to the area is Wuhan, and there is a professor at the University of Wuhan that does keep track of sightings, as far as he is able, but I have never been able to make contact with him.
