Who doesn't love to smile? How about making others laugh? Making jokes and bringing joy to people is not something everyone can do. Is it something you can do? In your daily life, give appropriate gifts to customers who have experienced problems and are feeling down to lift their spirits. The more you can make your customers happy, the more they will pay you. Provide them with the most suitable items based on their profiles and stories, and try to earn as much money as you can.
