"In this world, everything has two sides, positive and negative, Yin and Yang, good and bad. Whether it's about being a person or practicing martial arts, the principle is the same. Thus, from your consecutive Tai Chi Fist movements and your complexion, I could tell that your practice has harmed you."
"Young man, you're truly amazing. All the symptoms you mentioned, I have them. I've gone to the hospital many times, but they couldn't find any reason and just chalked it up to old age - after all, as people get old, it's normal to have some health issues. I didn't pay much attention to it. I never thought the problem would be here. Young man, how did you know all this?" the elderly man asked Ye Wudao curiously.
"I guess I'm half a doctor, so I noticed your condition right away. Elder, you shouldn't practice Tai Chi Fist anymore. If you really want to train, it's best to find someone to teach you, and definitely don't practice blindly on your own," Ye Wudao kindly advised him.
