Where Are We Going, Dad? is one of the most popular television shows in China now. Fathers now take an active part in their children's lives.

Five well-known fathers and their children travel around China, riding camels through the western deserts (沙漠), fishing in the east sea, and selling vegetables to get money back home in the southwestern Yunnan Province. One dad doesn’t know how to do his daughter’s hair, but he learns quickly and does it well now. Another one must stay with his son for three days in the desert, because he and his son don’t know how to cook, the two only eat instant (即食) noodles.

This show raises an important question for modern Chinese society (社会) —what is the role(角色)of fathers in today’s China? In the old days, children must obey parents’ wishes and look after them in their old age. But Chinese parents now think that discussing and respecting (尊重) their children’s choices may be a better way to prepare them for modern society. “As they raise their children, parents are growing up at the same time,” said Wang Renping.
