Scandinavia is probably the happiest place for kids to grow up. In kindergarten, kids only PLAY. Formal education starts when they are six. Not much homework and no exam pressure. They don’t even have grades before secondary school!
In Hong Kong, kids start to learn a lot of things already since they are 2 years old. They need to get prepared to enter good kindergarten, school and then university. After school there is lots of homework and tutorials. Childhood in Hong Kong is full of stress. However, life as an adult is even more stressful.
