According to the traditional custom, the son-in-law should "honor" his parents-in-law in three festivals (Dragon Boat Festival, Mid-Autumn Festival and Spring Festival) every year. For example, the son-in-law should bring zongzi, chicken, tobacco and alcohol during the Dragon Boat Festival. Moon cakes, chicken, pork, tobacco and alcohol should be brought during the Mid-Autumn Festival. Of course, the Spring Festival is even more indispensable. Although young people nowadays are not particular about it, they still have basic manners. As the saying goes, a son-in-law is half a son, which is true. New society, new fashion and adopted children are all the same!
