There are temples in three places in Changsha, one is Lushan Temple on Yuelu Mountain in Hexi, the other is kaifu temple near Xinhe Huaxia, and the other is a temple on the roadside of the development zone from East Station to Xingsha, which was decorated by my friend, but I just can't remember the name. The most popular is kaifu temple, where people queue up at midnight on the 15th day of the first lunar month!
