yeah, Chinese StarTalk program at Ole Miss Summer College for High School:

still time to apply and if your grades and SAT/ACT are high enough you could get a full scholarship.
also Ole Miss has one of only 12 Chinese Flagship programs in the whole country. I don’t think you can find anything better.
