Is the wifi in Tianyi Hotel free? Is it safe?

Not safe. According to the relevant information of Zhihu, the wifi in Tianyi Hotel is free, but it is not safe. There are three major security risks in hotel free WiFi. First, the public WiFi set by merchants has no basic online recording function, so it is impossible to access the Internet by real name. Once a cyber crime happens, the perpetrator can't be found, only the provider of WiFi can be found.
