There are several ways: 1: hire a nanny (if economic conditions permit)

2. Let the retired elders take care of it (I think most families do).

3. Let the children go to kindergarten for full care, and they can go to small classes when they are about 3 years old (that's how I came when I was a child).

4. In the worst case, take the children to work. Of course, this is not conducive to work. Finally, think about it.
