Although Guo Jingjing is a world champion and Huo is a rich boy, they are ordinary parents to their sons. The way they raise their children is very civilian. Instead of keeping their son in a greenhouse, they let them get in touch with nature and experience a different life.
I think they live in fireworks, especially grounded. They let their son transplant rice seedlings, just like Guo Jingjing can use a hair band of fifty cents.
