A video of two women arguing fiercely on a high-speed train in Chongqing has attracted attention. Some netizens said that parents should manage their children well in public.

In a child-friendly society, children should not be representatives of "noise" and "trouble", says Yiran. The ear pressure during takeoff and landing, may make the baby feel uncomfortable, and its expression - only crying - is not acceptable, she says. But adults are not babies and have the ability to control their emotions.
