I was puzzled by this question when I was very young, until I saw this sentence: red, orange, yellow, green, blue and purple, who trained to dance with color.

This is a sentence written by the librarian of Peking University in 1930s.

It also happens to correspond to the color of the gourd doll.

So I thought, is the author of Huluwa flexible because the word is widely circulated?

After all, it is an animation for children. If the design is too complicated, it is not good for children.

So the name goes directly from Dawa to Chiwa.

Therefore, the modeling colors are all in the order of poetry. Simple and easy to remember. Easy to popularize.

Because this sentence is written in seven colors and seven dolls.

As for why it is a gourd?

Because the gourd vine can bear a lot.

Song of Seven Sons is a group of poems written by Wen Yiduo during his study in the United States in March 1925, with seven poems, namely, Macau, Hongkong, Taiwan Province Province, Ahava, Guangzhou Bay, Kowloon, Lushun and Dalian. The poet personifies these seven "lost lands" into seven children who are far away from their mother's arms, and cries with their children's voices about their strong feelings of being forced to leave their mother's infancy, suffering from foreign bullying and longing to return to her mother's arms.
