Saozi noodles are a Han snack in Shaanxi Province.

According to legend, King Wen of Zhou's parents died early when he was young, and he was raised by his brother and sister-in-law.

Once, King Wen of Zhou led his army to encounter a pouring rain during an expedition, and the wind chilled his bones. He took hundreds of medicines but saw no improvement, and was bedridden for several days.

When her sister-in-law learned about it, she went down to the cupboard and rolled out a bowl of hot noodles for King Wen. King Wen was sweating profusely and full of energy. Later, he named it "Sister-in-law Noodles" in memory of her sister-in-law.

Therefore, Saozi noodles are also called "Sister-in-law noodles" or "Shaozi noodles", and "Shaozi noodles" may be derived from the homophonic transformation.
