Does Chongqing Jiulongpo have those foot washing cities? To be formal, it is best to look at high-end and talk about business.
Fuqiang Foot Wash City, Ruby Foot Wash City and Zule Youdao (South Garden). I haven't been anywhere else. Zule Youdao has been there several times. It's pure and formal, and then it feels quite high-end You can massage anything. If you want to talk about business, you can go to Zule Youdao, which may meet your liking.
