It is said that during the Double Ninth Festival, Hua Tuo, a legendary doctor, visited a local wine house with his medical students for a drink. There, he saw several teenagers engaged in a crab-eating competition. They munched enthusiastically, piling up crab shells into a small tower. Hua Tuo thought, "These youngsters are unaware of the health risks; as crabs are cold-natured, overeating will make them sick." He actively offered some advice for them. However, the teenagers were so absorbed in their competition that they ignored Hua Tuo's counsel ! One of them even sarcastically said, "Are you greedy? I'll break a piece for you to taste." Hua Tuo sighed angrily and turned to the restaurant owner, saying, "You can't sell any more crabs to them. If they eat too many, it could be fatal."
