Winter vacation is easier to gain weight than summer vacation, because the Spring Festival is coming. All the food and fun are here. Basically don't eat midnight snack, don't play all night, don't eat more snacks, go to bed early and eat 7 minutes full. 8 kg is no longer a problem. Other methods of losing weight are not applicable, especially taking medicine and running in the Spring Festival and winter, which is even more unrealistic, so just control your work and rest and pay attention to detoxification.
