In 22 1 year BC, Qin Shihuang swept the six countries and realized the unification of the four seas. In order to consolidate the unified situation and strengthen centralization, he promulgated a decree to unify the monetary system, stipulating that yuan money is the standard system. Since then, round square coins have been circulating in China for more than 2 100 years, and even affected neighboring countries such as Korea and Japan. People even nicknamed coins as "Kong Fang brothers".

Round square hole money has a beautiful appearance, which contains the cosmic mystery of "the sky is round and the place is round" and the philosophy of life of "the outer circle is inside". The ancients believed that the "sky" was round, the height was vast, the depth was transparent, and the "ground" was square, calm, regular, simple and heavy. Used in life, it is "the outer circle is the inner side", which is harmonious and sophisticated to people and things and abides by the principles of the world. It can be said that the square is.

When we carefully study the origin of round square hole money, we find that the design of this shape is completely out of the need of manufacturing and carrying. During the Warring States period, coins were basically cast by melting. For the convenience of carrying, the ring coin was first designed. However, when the edges of coins need to be filed and polished, the round hole in the middle often makes them unable to be fixed, so people change the round hole in the middle into a square hole, and put several coins through a square wooden stick and polish them together, which greatly improves the efficiency.

Mr Yao Yao famously said that a person should be "outside the circle and inside the square". He is engaged in modern literature, but he is also full of the spirit of traditional literature. You should have principles in mind, such as the question raised by this friend just now. Intellectuals should be independent. Without independence, there will be no academic progress. But you shouldn't quarrel with others everywhere because you have some independence and unique opinions. We now call these people cynics. Fenqing has his lovely side. He is sometimes one-minded. He thinks he can master the truth, and he doesn't look back on his own sources of knowledge. He is like a man with many edges and corners, and uses these edges and corners to collide with others. China's ancient coins, big bills, make sense. "The outer circle is inside" symbolizes the humanity of China people. Don't cut people on the outside, live in harmony with them and be tolerant. "The Analects of Confucius. That's what I'm saying. Laozi advocates "square without cutting" and "gorgeous without shining" Today, we live in an era when the cause overwhelms humanity. If you meet someone with a different point of view, don't treat him as an enemy, but don't change yourself easily. You can be friends. This is my principle in dealing with people. Only by keeping your heart independent can you have strong vitality.
