Shang Yun Huanghuai Health Punch can't be opened.

1, the network delay didn't come out. At present, there are too many people logging in, which leads to system crash. I wish I could log in and open it later.

2, caused by the mobile phone network, if the mobile phone network speed is poor or there is no Internet access, this situation will also occur. It is suggested to check the internet connection status of the mobile phone, or disconnect the mobile phone network and try to reconnect it, and then reopen the electronic health card.
