ZHANG Yishan, 18 and Yang Zi, 17, who played Liu Xing and Xia Xue in the popular sitcom, Home with Kids, have always seemed inseparable. The two child stars are grown up now and they started college this month. Both were admitted to Beijing Film Academy and put in the same class. Yang registered (报到) on her own and things went well, while Zhang took longer. He even had to rush to a photo studio (照相馆) in the college to get enough snapshots (快照).
