Mac Input method is always the default Chinese, how to set up in English?

Recently a colleague in Dreamweaver, writing CSS style, the default is always Chinese, cut to other windows, and then cut back, it becomes Chinese, always click the toggle button, time is particularly annoying.

Find some methods on the Internet and finally find a valid one.

To summarize is: first set the system language into English, and then restart, and then re-set to Chinese, and then restart. (if not, just do not restart, try it)
