There are many records about particles in China ancient literature, and the resolution of particles is very different, such as

1. Zhou Li's "hemp, millet, millet, wheat, millet (bean)"

2. Mencius's "rice, millet, millet, wheat, rice"

3. Manage "millet, rice, rice"

4. Chu ci "rice, millet, millet, rice, hemp"

Rice and wheat are still the main foods in China. In China, rice (rice) cultivation originated in the Shennong era in southern China about 4,700 years ago. The cultivation of wheat (barley and wheat) was introduced into North China in the late prehistoric period or before Pan Geng moved to Yin.

As for the millet, millet and grain in the grain, they all belong to "millet". "Millet" is one of the important grains in the north, and it is rarely planted in the south. "Small" basically includes millet and millet.

Millet is not what we often eat today, but rice seeds and yellow rice. Corn is a crop introduced from the west only in modern times.

Peas are beans, and beans in grains are not all beans, but soybeans. Soybean was called glutinous rice in Zhou Dynasty, and it was called bean since Qin and Han Dynasties.

Hemp in grain refers to hemp. The seeds of hemp are nontoxic, but the leaves are toxic, so it can be used as food.

At present, we often grow less than five kinds of cereal crops, but if we take our main cereals and their by-products, I believe everyone will agree that they are rice, millet and wheat. Others, such as barley and corn, can only be used as miscellaneous grains and feed.

What are the seven emotions? "Li Yun" said: "Happiness, anger, sorrow, fear, love, evil and desire can all be learned." It can be seen that emotion is an emotional expression or psychological activity of emotion, and desire is one of the seven emotions. Strangely, the "seven emotions" of Buddhism are almost the same as those of Confucianism. They all refer to the seven emotions of "happiness, anger, worry, fear, love, hate and desire" and put desire at the end of the seven emotions. The theory of traditional Chinese medicine has changed slightly. Seven emotions refer to seven emotions: joy, anger, worry, thinking, sadness, fear and surprise. Excessive excitement of these seven emotions may lead to imbalance of yin and yang and stagnation of qi and blood, which may lead to various diseases. It is thought-provoking that Chinese medicine does not include "desire" in the seven emotions.

So, what are the six desires? Lu Chunqiu-Guisheng first put forward the concept of six desires: "The so-called whole life is suitable for all six desires." So what exactly are the six desires? Gao You, a philosopher in the Eastern Han Dynasty, commented on this: "Six desires, life, death, ears, eyes, mouth and nose." It can be seen that six desires refer to people's physiological needs or desires. People should live, be afraid of death, and live with flavor and color, so they should eat with their mouths, taste with their tongues, see with their eyes, hear with their ears and smell with their noses. These desires are innate and can be learned without teaching. Later, some people summarized this as "seeing desire, listening desire, fragrant desire, taste desire, touching desire and desire". However, the Buddhist theory of great wisdom is far from it. It holds that the six desires refer to lust, appearance, dignity and posture, speech and sound, fluency and human desire. Basically, the six desires are defined as the six natural desires of laymen for the opposite sex, which is what modern people often say.
