You can't,because when you leave U.S.A, the airlines staff will collect your I-94 and submit to USCIS,then the information of your leaving will be put into the computer system of USCIS,you can't enter USA again without a new visa.
If you go back to China from Mexico, the way you imagine maybe work.
