\u4e00-\u9fa5 
unicode encoding, an encoding included in languages ​​all over the world. (Commonly used in the internationalization function) 
\u4e00-\u9fa5 may be a condition used to judge whether it is Chinese. There is no introduction to this, just to find which country's language is in which range. 

+ can match 


''' 



''' repeatedly

? The preceding character can appear at most 0 or 1 times
