You can try to use mung bean powder, the supermarket can be bought, with mung bean powder and pure water and together, every night before going to bed like on the mask to touch the face. A week later there will be changes, in addition to your usual diet to eat more vegetables, the best for defecation is seaweed, fresh seaweed can be bought in the supermarket, cold seaweed is the best! Drink more water, sleep to ensure seven hours a day.
