Changed to Changhuan APP.
I will analyze the reason why Dehui Tianxia cannot be opened this time. It is mainly to avoid risks, and the name has been changed. However, the previous account cannot be logged in again. Now it is renamed Changhuai, and It has more functions than before and is more convenient to use.
The newly renamed Changhai not only allows balance repayment, but also empty card repayment. In addition to the first time, it also offers Baitiao, Huabei and other services.
