Use this script to auto-reply "囍" in WeChat groups.
I do not really know what is the exact meaning of this character. It is often used to express a sense of auspicious, a pursuit of happiness, an ultimate destiny of joy and luck, among Ingressers in Peking University.
The function is too simple and straightforward: once anyone (except you yourself) in the WeChat group send a message containing the character of 囍, you will automatically reply a 囍.
Thanks to itchat project, WeChat APIs are provided. With this package, I can easily define an auto-reply bot within ten lines of codes. 囍！
The script is written in Py3k, and depends on the itchat package.
