That's all well and good, but when the items, triggers and variables are all in Chinese its not that straight forward. to know what you are changing (unless someone has made the variable translation file).you can use :You must be registered to see the links
to edit your save files and you can also use "RpgMakerSaveEdit" a downloadable save editor.
You can alternate between the two to pick what to edit as both have their own strengths.
