I have the fix.
Open up World Editor and import war3map.w3a under Object Editor
On the main editor click file, export strings.
This text in the *.wts (strings) can now be easily translated in Google translate. Unfortunately you can only edit around 230 lines at a time.
Just keep copying, pasting,translating, and pasting back into the original file, overwriting the Chinese text with the English.
Save your file after each paste. It's also a good idea to import your strings into the map to make sure you didn't screw up the formatting.
*Do not navigate through the abilities and/or edit any abilities while you are still translating. Every time there is an ability edit, the strings add another number, goofing up your saved work.
If you are looking to translate the whole map you would have to deprotect it and be able to edit it in WE. I think to play this map properly you would need to do this.
Here is a sneak peek after translating a small portion.
