The process of changing subtitle files from one language (Chinese in this case) to another (English) is super easy.
You've got multiple options.
Option #1 - Use the Auto-translate function in the program called Subtitle Edit. (See attached picture) It's so easy that I won't even go into detailing how to do it. (Lots of instructions can be found online.)
Pro - Super easy
Pro - Fast
Con - You can only do one or two auto-translations within a given period of time. (This has been my experience, but I don't know the actual rules)

Option #2 - Save the file as a .txt file and cut and paste lines into Google Translate.
Pro - Super Easy
Con - It has a 5000 character at a time limit, so it's slower and you can only translate 5000 or fewer characters with each paste.
