The names Zhang and Wa were first seen in "The Book of Songs·Xiaoya·Sigan". This is an ode to congratulate nobles for building palaces. There are two paragraphs in the poem:
When a man is born, he will be given a bed to sleep on, clothes to wear, and a king to play with. He wept and wailed, Emperor Zhu Fusi, the king of his family.
It is the place where a woman is born, the place where she sleeps, the clothes she wears, and the tiles she wears. Nothing more than lack of etiquette, only drinking and eating, no parents to blame.
Translation: After building this new palace, if a boy is born, he will sleep on the bed, wear clothes, and play with him. Listening to his loud cry, he will definitely be successful and have a noble status in the future. At least as a prince, he might be able to wear the Emperor's glorious clothes (Zhu Fu, also known as the Emperor's clothes).
After the new palace is built, if a girl is born, she will lie on the ground, wrapped in swaddling clothes, and play with the pottery spinning wheel. When this girl grew up, she became a good expert at housework. She did not make her parents angry, but she was also good at her husband's family. She was praised as a good wife and mother who never caused trouble. That is, doing things will not go out of style).
