Hi @Max Chen,
Thank you for providing more information about the issue. Based on your response, it seems like the language detection service is not able to correctly identify the language of the text because it contains both English and Traditional Chinese characters. This is causing the service to return a "zh-chs" result instead of a "zh-cht" result.
I tried with your text with and without English characters along with Chinese characters. So, the Language Studio able to detect as "zh-cht" (see below image). I suggest that you separate the English and Traditional Chinese text into separate strings and run each string through the service separately. This will ensure that the service can correctly identify the language of each string.
Hope this helps. Do let us know if you any further queries.
