It seems that I have never examined my body like today; on the one hand, I used to think that I could accurately distinguish the good and bad of natural elements, what kind of wind is good, what kind of rain is good, and what kind of marble pier is better for my irregular menstruation; but today, when I saw myself in the mirror, I found that I had been struggling with this body for years. When I was younger, this cold condition might also have been present, but I paid more attention to my periodic oral ulcers; Hua Su pills, vitamin B/C, watermelon frost, and others, all came into play. But later, it couldn't be considered as a cure. It's been a long time since oral ulcers have appeared, just when I was hesitating whether my entire oral cavity was already covered with ulcers, last month, a small sore suddenly appeared in my mouth, but it healed quickly.
