(1) Boast "Niu" refers to "snail", which is a common name. In Erya Insect-eating, it is called "cockroach", and Guo Pu notes "snail". In the jade articles of Gu Liang Wang Ye in the Southern Dynasties, there is also a note that "snails are cockroaches". As the abbreviation of "Mao", the pronunciation of "Mao" is the same as today's "fish", and Lu Deming, a famous exegetist in the Tang Dynasty, clearly put forward in his classic interpretation: "Mao, Liu,"
In ancient times, people often used the shells of gnats as blowers, which made a loud noise. As a result, he later boasted with the metaphor of "blowing". The pronunciation of "Mi" is not only similar to that of "Niu", but also commonly known as snail, which is related to the fact that its head has tentacles similar to the head of a cow. In addition, cows have the characteristics of big body and great strength, so "blowing rice" and "bragging" are also interlinked.
Bragging means blowing flies, which can also be proved by the Buddhist term "blowing snails" In Ci Hai, there is an entry "Blowing the French snail", which is marked as "The French snail is a snail shell, and the sound energy is far away", which is widely accepted by the public as a metaphor for the Buddha.
(2) According to the Records of the History of Yuan Dynasty, the Yuanjiang Stone Mill case only attacked Xuzhou in Song Dynasty (now Yibin City, Sichuan Province), and Sung River crossed the river, and Yuan Army was not allowed to cross the river. "The case only gathered cowhide in the army, making it disperse and kayak, taking advantage of the situation to fight, breaking its army, taking its ferry, and helping its division with a pontoon bridge." At that time, Mongolians who grew up in Mobei grassland could only ride horses and could not build ships. Whenever they wade, they regard Huntuo as a boat. So, what is mixed trust? Ye's "Grass and Trees" said: "Northerners kill calves, cut a hole in the spine, and take off the head and meat one by one, and the skin is all. Kneading dough is used to hold cheese wine, which is called muddy. " Mixed tuo is the skin of a calf. Because there is only one hole in the back, other places are still intact, so there is no danger of spilling wine and milk. When crossing the river, just blow at the small hole with your mouth. After the cowhide expands, tie the small hole tightly with a rope and it becomes a boat. So there was a "brag" from then on. At first, it was just a bragging bag.
