As far as I know, Changli Bohai Tao Xin Bath Center is not a formal bath center. There are several reasons: First, judging from the decoration of the bath center, the bathing environment and facilities in Tao Xin of Changli Bohai Sea are relatively simple, which is insufficient compared with the general formal bath center. Secondly, the business license information of Changli Bohai Tao Xin Bathing Center shows that the bath center is not registered in official website, nor has it been certified and approved by relevant departments. Furthermore, there are some problems in the business promotion mode of bath center, such as telemarketing, which may also cause consumers' distrust. Therefore, I think Changli Bohai Tao Xin Bathing Center is not a formal bathing center.
