Programs in China Late March/Early April to June/July?

S1 is likely to graduate a quarter early from UC. He’s pretty fluent in Mandarin and
has an eye toward visiting China before starting into his career. Might there be a
study abroad in China that would fit with his quarter schedule? Most I’m seeing
appear to be semester based starting in January. He’s a CS student - so another
option would be an internship (he’s already done some for Big 5 techs). Any
thoughts appreciated for some program roughly 3 months in length.
