Quite a wonderful question! Besides being illegal, what can't be done? If you are not lazy, you can learn to cook, bake your own desserts, and then go shopping, exercise and so on; If you don't want to go out, watch TV, play online games, read books, listen to music and clean up the housework; If you want to improve yourself, you can charge; If you want to add fun to your life, you can keep pets and play with flowers, birds, fish and insects. If you are really bored, you can go to Taobao and watch a live broadcast or something.
Life is full of fun, as long as you have eyes and brains to find fun, as a cross talk says, everything can be set, and the key is whether you take the initiative to find it.
