Dear Jiaxu, I can commit your changes to master (as this patch is for master,
to be lyx 2.5 one day), but I believe should have been updating zh_CN.po file
for 2.4.x branch. You probably started with wrong file?

What I see at the moment is that zh_CN.po in master has ~1400 untranslated strings,
while 2.4.x ~250 untranslated strings. So sooner or later the 2.4.x po file
should be copied into master, but that also means your current changes to master
will be lost.

I can do 2.4.x -> master copy now so they are more in sync... But again the changes
you sent will be lost...
