For Mainland China-based company, you may use QBO Global version for China

You may change the language setting to Chinese later in Gear > Account and Settings > Advanced > Language.
Currently company only provides native setting for QBO Hongkong version

Your main issue will be the migration path. You can not migrate directly from QuickBooks Desktop to QBO Global version. You will need a migration tool, or purchasing a 3rd party conversion service.

Just my 2 cents.
