I've installed v154 Eng version first, then installed the Schinese language pack (zen-cart-v154-Chinese-simplified-utf8). I would like to add one more language selection (Tradition Chinese), (i.e. Eng / Simplified Chinese / Traditional Chinese) then I installed the Schinese pack again but changed all the related folders to other name and changed all contents from Simplified to Traditional.

But I'm not sure how to do under the folder Email. I find there is an existing folder "GB" under Email, I guess it should be used for simplified Chinese. I wonder what folder name I should create for traditional Chinese.

Could anyone help me? Thanks very much!
