The source of combined Chinese characters can be traced back to the runes used by monarchs to convey orders or recruit troops in the pre-Qin period. Usually, several seal characters are combined, carved on bamboo pieces or wooden boards, and then cut in half, each side holding half, to test the authenticity. In the Han Dynasty, Taoist priests borrowed it from the so-called Fu Zhuan, which was called "Wen Fu". Since the Song Dynasty, compound words have evolved from Taoist symbols into a means for adults to express their desire to avoid evil and seek happiness. Pronunciation is generally to read four words; Monotonicity is created by individuals and has no authority.

The most common combination of Chinese characters is this golden two thousand:

Wedding auspicious words-harmony between husband and wife

Seven stars are shining high.

A bumper harvest of grain

May everything go well.

Peace in the four seasons
