Vim python syntax error cannot be highlighted correctly

As described here, I use the dein program to let vim highlight some dirty writing manners in python codes. 

 

However, when I sshed from my macbook to a linux machine on a xterminal, I did not obtain correctly hihglighted parts in my python script, as such:

f:id:ar125s:20210425104020p:plain

What expected was this:

f:id:ar125s:20210425103958p:plain

Comarping between these two representations, we know that we could not find the actual location of the bad writing in the first one.

I added the following sentences in .vim/colors/desert.vim which I set as my colorscheme in .vimrc,

f:id:ar125s:20210425104159p:plain

because I found these hightlight terms related to syntax were not linked as expected. I did not find the source of this fault, but after this addition, I had the correct highlighiting as in the middle picture of this brog.
