My name is
Talha Faisal when I try to translate my name into Chinese (traditional) language, I got 塔拉費薩爾
Ta la fei sar not
How can I write my name in Chinese?
As the OP has clarified that the "h" in the name is not silent, 塔拉費薩爾 is not an accurate transliteration because it's missing the "h" sound. 塔爾哈·費薩爾 would be more accurate.
Note that Chinese is full of homophones so it is not the only possible transliteration. However, the characters used here are all commonly used and quite conventional in transliteration so I would say it's quite safe.
