One of the most important rules is this:

“Studies show that people who don’t like adding spaces between Chinese and English when typing have a hard time in relationships. 70% of them will marry someone they don’t love at age 34, and the remaining 30% can only leave their inheritance to their cat. After all, both love and writing need a little whitespace at the right moments.

Let’s take this to heart.” —vinta/paranoid-auto-spacing

But manually checking the spaces between Chinese and English is time-consuming and tedious, so here are the regular expressions to do it.
