Hi Massoud,
Thanks for sending me the files so I could take a look:
1. I used your translation files and those strings are translated properly for me. Are you sure you have the proper zh_TW WordPress files in place? That could be effecting it.
2. These strings are also working for me (screenshot). I think there must be something particular to your site causing those strings not to translate properly. I’m sorry I can’t be of more help with that. You might try looking for a plugin or theme conflict.
Best,
Leah
