python text editor: re.sub ------- read the text, and save the removal of specified characters

Now there is such a mission:
we have a text, which reads as follows:

 

ws0012cs3d4 this, there. 3 is A!? Some a text Z this ...

 

There are text in English punctuation, English characters, numbers, letters, Chinese, spaces, etc., now we need to read the text line by line, in front of the label (ws0012cs3d4) remains unchanged, after the text filter to include only Chinese text data, and then put together again numerals and text, the following form:

Here is some text ws0012cs3d4

　　

Saved in a new file.

code show as below:
