On 20 17, I went to Manyue Music Circle, and I can go to Manyue Music Circle in 2022. Manyuele rings are generally valid for about 5 years. After 5 years in Sheung Wan, you need to go to the hospital to get the ring. The best time to remove the ring is five to seven days after menstruation is clean, because this is the most stable time of endometrium, and the pain of removing the ring is the least and the safest.
