According to Baidu Encyclopedia, the coffin building in Gulangyu is actually the Guancai building, which is the tallest building in Gulangyu. Located at No.6 Bishan Road, Gulangyu Island, it was designed by Dutch designers and built at 193 1. There are two versions of its name. First, because the top of it can see the most beautiful rosy clouds in Gulangyu, and second, because its roof looks like a coffin. At that time, people joked that it was "coffin building", but the name was not pleasant to listen to, and later it was homophonic as "official building" Its appearance is a bit of the shadow of European Renaissance architecture. Some people say that the roof is like the bride's sedan chair and jokingly call it "the bride's darling". It is a mysterious and romantic place in Gulangyu.
