The next day, Xu Cheng went on his morning run again and he chose the exact same time as yesterday. When he went to the park, he saw the elder already waiting for him while practicing Tai Chi.
Tired from the run, Xu Cheng still went in to drink some tea. But after taking a sip, he was a bit dissatisfied, "Elder, what happened to the tea?"
The elder snorted. "You little brat really did waste the dahongpao, so I just gave you normal oolong tea instead. You would chug it down anyways so it doesn't matter what you drink."
After Xu Cheng drank two cups of tea, he squatted down to take a break as he watched the old man. After watching for awhile, he asked in curiosity, "Is Tai Chi really useful?"
The old man replied, "It depends on your mentality. If your heart is impetuous and you can't calm down, then it will be useless no matter how much you practice. Tai Chi can be regarded as an exercise to cultivate your soul and train your temper."
