In the Three Gorges of the Yangtze River, archaeologists unearthed a huge object with poor craftsmanship. It turned out to be Mai Zi Zhong Fei. Another piece of waste was unearthed! Mai Zi, whose name is Dou and whose courtesy name is Zhong Fei, is a thinker and inventor in my country who is full of food and nothing. Just when everyone didn't know how to deal with this huge and useless thing, a child who is suspected to be Mai Zi's 18th generation descendant, McDull (voiced by Guo Junyan/Zhang Zhengzhong), was in a daze in Hong Kong with his mother Mrs. Mai (voiced by Sandra Ng/Song Dandan). McDull is very slow, very well-behaved, and very dull. He was assessed as having multiple low intelligence. Mrs. Mai is not much better. She has been rushing around for half her life, but she has always been in vain. For herself and for McDull, Mrs. Mai decided to bring McDull to the mainland to make a living. When they arrived in Wuhan, Mrs. Mai reluctantly sent McDull to a martial arts school "Taiyi Chunhuamen" in the mountains for boarding. Life in the mountains is hard, and the head Taoist (voiced by Anthony Wong/Zhang Likun) is dull. McDull has no interest in martial arts. His greatest pleasure is to sneak into the alchemy room with his classmates to cook instant noodles. Fortunately, McDull has an amiable assistant teacher "Brother Xiong Bao" who takes care of McDull from time to time. The "World Kindergarten Martial Arts Competition" is about to be held. The children of "Taiyi Chunhuamen" are weak and look forward to being beaten. In the "International Kindergarten Martial Arts Competition", McDull will face the children who are good at fighting from all over the world. At this time, the giant thing of McDull's ancestor McZhongfei suddenly rang. It turned out that this was a big clock that equaled one second per year and only sounded once every 3,600 years... Great achievements are made without success, and great achievements are made late. McDull suddenly realized the truth of Tai Chi and even his own life...
