Although there are currently issues with training in Chinese, I have found a workaround through testing. I can use all-English training files but request the chatbot to respond in Chinese, specifying traditional Taiwanese Chinese and using appropriate terminology.
The chatbot can provide accurate responses and is in line with natural language. I hope that in the future, there will be faster support for Chinese training files and an increase in the number of training files per chatbot, as currently, each chatbot can only accept up to three training files.
I will give it five full tacos if there is more comprehensive support for Chinese training.
