The most common number format used in China is 3/4/4 (XXX XXXX XXXX). Dash (-) is never used here.
In Google's libphonenumber the metadata is like this:
Id ; National ; Carrier ; International ; Local ; National Prefix Optional ; Comment
...
mobile_3/4/4 ; "XXX XXXX XXXX" ; "@ XXX XXXX XXXX" ; "XXX XXXX XXXX" ; ; ; "Mobile range"
