Over the rainbow, the back door. According to the information in Songgang, Shenzhen, I know that an alley at the back door above the rainbow in Songgang, Shenzhen is fun, and an alley at the back door above the rainbow in Songgang (opposite to those who want to take the bait) has a barbecue style of wooden houses, which feels like a tea shop. It looks neat and clean to the naked eye, but the floor is easy to slip.
