Many times I went to Songjiang and passed Guangfulin Site Park, but because of the time relationship, I couldn't make it. When I came to East China University of Politics and Law by chance, it was more than 9 p.m. to finish the work. Seeing the mysterious color of the Guangfulin site under the night, I was deeply attracted. I could not help walking towards the site. The underwater buildings were mysterious and silent under the cover of the night. Guess how many stories are hidden behind this building...
