Jay Chou and Song Zuying's "UK" duo created the biggest topic of this year's Spring Festival Gala, and prior to Song Zuying's appearance, little boy Hou Gaojunjie, who partnered with Jay Chou, astonished the audience. Our reporter made contact with this 9-year-old boy, nicknamed Baby, and his agent in the first instance. It turns out that as early as 3 years ago, Baby had already become a contracted artist with Jay Chou's mainland China record company, becoming Jay Chou's junior in the same school, and was referred to by staff members as "Jielang".
