@biyao73 , the article you refer to is indeed applicable to you , provided you have not any steps to (a) declare that you are no longer learning i.e. either in school or practical training like CPT/OPT and (b) that you have taken no steps move yourself from "temporarily" in the US to a more permanent posture like applying for permanent residence.
Thus assuming that you are still on your F visa and have become a Resident for Tax Purposes only because you have passed the SPT, you are still eligible to assert article 20 of the US/China tax treaty conditions to exclude the first US$5000 of annual income from US taxation. Also note that the article does not put a time limit -- just "reasonable time ".
Where I have worries would be the case where one Resident for Tax purposes student marries US citizen--- it is murky water and IRS will decide on a case by case basis depending on exact facts and circumstances.
Does that help ?
