(Possibly deprecated) automated wechat using wx.qq.com, get and send most types of wechat content and process them. Also attached a chat machine which can remotely calculate Mathematica code through wechat.

Human-like circuit simplification, calculate the resistence of a network.

Automated key press, mouse move etc.
