Frequency character is a Chinese character with rich meanings, and its basic meanings include repetition, continuous multiple times, juxtaposition, together and so on. In the formation of Chinese characters, frequency words are composed of page words on the left and frequency words on the right, where page words mean head and head, and frequency words mean continuity and repetition.
When we understand the meaning of frequency words, we can start with its composition. The words on the left represent the meaning of "head" and "first", indicating that the frequency words themselves are related to repeated actions or situations. In the development and evolution of Chinese characters, the meaning of frequency words gradually changes from the continuity of the head and the first place to the continuity or repetition of anything. So frequency words can represent any situation that appears many times in succession, such as frequent occurrence, frequent continuation and so on.
Frequency words can also mean juxtaposition and connection. In ancient literature, the word "frequency" is often used to mean that two or more things come together, such as "Hundred Schools of Northern Society", and the word "frequency" in the group of gods means that all kinds of beautiful things will walk with God.
When writing common words, we should pay attention to the starting and ending position of each stroke, as well as the spacing and angle between strokes. At the same time, it is necessary to keep the correct writing posture, flexible wrist and moderate pen strength, so that the whole word looks harmonious and beautiful.
