Unlike what I imagined, I thought it would be like Sapporo's underground street, where there are many small shops, people coming and going, bustling and lively. It's more like a boutique street, with exquisite decoration. Every shop is like a display window. The boutique presents, and the customers entering the shop are limited. The ceiling of the underground street is decorated with sparkling lights, and there are time and space tunnels. Sense, due to the relationship between time, only a few hundred meters, maybe the back of the wonderful is not the same.
