What mysterious events happened in the three UFO houses?

According to Lao Yuzai's comments in the message area, let me make it clear ~ The case name is Sanzhi Longgang International Leisure Club (also known as UFO House). In the late 1960s, the development information of the person in charge of the development company Yuzhou Qianwei Company was updated. This design was designed for Mr. Ye, who was originally an employee of Wan Li Tiangong Company, and the UFO House in emerald bay was also his work. He is about 60 years old at most this year, when he was quite young. 1984 immigrated to the United States. The original idea of RC structure was designed by Mr. Ye's younger brother who was still studying in the Central Plains Architecture Department. The application for signature and architectural photos was stamped by an unknown architectural architect (Mr. Ye himself forgot) and submitted for review (architectural photos). [Reasons for Closure] 1969 (AD 1980) The oil crisis and economic panic led to the closure of Yuzhou Qianwei Company due to poor turnover, and the development case was closed. Stop work at this point, and the property right belongs to the creditor bank. When the work was stopped, only half of the basic structures of more than a dozen FRP oval buildings were assembled, and the remaining FRP balls were scattered all over the place, without any planning and procurement drawings and architectural structure drawings. The three-story building structure on the right has not been demolished, and the entrance gate and cement dragon are almost the same as they are now, which is a relatively complete rumor. As for whether 10 thousand bones were dug up when the construction site started in those years, I have never heard of it. The local coastal area was originally an ancient execution ground under Japanese occupation, but the news quoted the legend of three branches of the older generation, calling it the ancient battlefield between the Qing court and the Spanish army. Personally, I think it's too distorted. The ancient battlefield of naval warfare is not here. This place is full of rocky shores and has not yet been connected to the sea. At that time, fresh water batteries could not be managed here, and people with a little military knowledge could understand. Moreover, compared with the excavation area of Cosmos in the past 60 years, it should be great to have more than a dozen ancient execution grounds.
