Why is there a saying that "great powers are stable"? What does this sentence mean?

This problem should start from ancient times:

1. This proverb comes from ancient times, which means "big hands, big feet, big ears, wide shoulders and fat buttocks" respectively, while the three are "thick waist, thick legs and thick neck".

Big hand: A hand as big as a dustpan is a symbol of wealth gathering, so there is a proverb that "big hands can gather wealth". Bigfoot: A pair of Bigfoot is an indispensable trunk for working people. As the saying goes, "Bigfoot is everywhere." Big ears: big ears are blessed. "Yan Guangji" says: "The ears are four inches big, and the shoulders are high." So most people say that they have money in their ears. Shoulder width: In the ancient farming period, working people preferred men with shoulder width, so there was a proverb that "strong arms are not lacking". Fat hips: Because people with big hips sit steadily, there is a proverb called "big country is stable" (another point: most women gather wealth). In fact, it is more appropriate to say that the foot is big and the country is stable than the foot, because this statement can be traced back to ancient times. In ancient times, if a man was five big and three thick, it was a very good compliment to him. This is a good word. There is a saying in the countryside: the head is small and floating, the feet are long and bitter, the hands are big and dry, and the feet are big and stable. It means: a person with a small head is destined to wander all his life; If a person's feet are long, he is doomed to work hard all his life. In other words, people with small heads and long feet have a bad life and can't enjoy making a fortune. With a big hand, you can control the overall situation and turn around Gankun; A person with big feet is steady and can control the current situation. In other words, people with big hands and big feet can better handle some things in life, work and feelings, live smoothly and enjoy the blessings they deserve.

? 3. Whether in ancient times or in modern times, from a biological point of view, fat people sit steadily and the lower plate is stable. As far as human senses are concerned, big people give people a steady and steady way of doing things and are easy to gain people's trust. "
