Hi Tran Quang Phuc,
1) The target language in the file you posted (the csv and the txt) seems Simplified Chinese to me so I don't understand why you said destination language is Chinese (not simplified) .
2) In your case, maybe you should buy a major CATO tools such as SDL Trados 2014 or 2017 version, there is some menu in this software that allows you to load various kinds of machine
translation API such as Google Translate or alike.
See the screenshot below.

3) So far you cannot load API of the custom model trained by Google AutoML Translation.
4) You may consider outsourcing the job to me if you trust me and the rate is reasonable.
