Thanks for your kind help. Chinese, simplified and traditional, translation have great improvement. There is one question about Chinese language code. Can I suggest using zh-Hant-TW for Chinese written using the Traditional Chinese script at Taiwan. According http://www.ietf.org/rfc/rfc5646.txt Quote few paragraph for you from above page: Language subtag plus Script subtag: zh-Hant (Chinese written using the Traditional Chinese script) zh-Hans (Chinese written using the Simplified Chinese script) hus, "zh-Hant-TW" is more specific than "zh-Hant". Language-Script-Region: zh-Hans-CN (Chinese written using the Simplified script as used in mainland China) -- Wishing you all the best. . . .
