Long summer is a dietary custom, and fish say they want to eat "Chinese food".

It counts. In fact, we are talking about rice amaranth and amaranth, common vegetables in Jiangnan. In daily life, there are two kinds of amaranth: red amaranth and white amaranth, which are called red amaranth and white amaranth in Compendium of Materia Medica. As for how to eat, it is best to put more garlic when boiling water, or stir-fry it.

In English, amaranth is called "China spinach", which shows that it is unique to China, at least not in Britain. Why else is it called "China Spinach"?

However, it is generally called "water spinach" in the south of the Yangtze River. In Compendium of Materia Medica, "water spinach" and "amaranth" are regarded as two plants, saying: "Water spinach grows in the south, and the grass in the country is there." People in Ningbo call spinach "wild rice amaranth". Potatoes may be wild rice amaranth, and they can only eat buds. The thick stalks planted by villagers are "potato stalks" before flowering, steamed with stinky brine and delicious after meals and drinks.

"Water spinach" is invisible in many words. The predecessor's note "Qing Palace" said that Zhu "offered Ipomoea aquatica after each drink". Yang Wanli has a poem "Luo Zhongxian sends a long sentence to thank Ipomoea aquatica".
