The lentils in our area used to be just the kind of "wide lentils" that Beijing people said. Zheng Banqiao wrote a couplet: "A yard full of spring rain and vegetables, full of autumn wind and flat tofu pudding." When it comes to this lentil. This conversation is about a poor family with no worries about food and clothing. Wealthy families don't grow vegetables and lentils in the yard. There are two kinds of lentils: purple flowers and white flowers, with more purple flowers and fewer white flowers. Tofu in Zheng Banqiao may be purple. The skin of purple lentils is also purplish, while white lentils are light green. They all taste the same. If it is only medicinal, it must be "white lentils", and the medicinal properties of the two lentils may be different. Lentils bloom in early autumn, then bear horns and can be picked at any time. Banqiao said that "the autumn wind is full of eyes", which gives people the feeling that it is already late autumn. Painters who draw flat bean curd like to draw a weaver girl, which is a seasonal thing. It's cool in summer and the moonlight is like water. Listening to Weaver vibrating his feathers in the sand on the lentil stand is very emotional. There are red lentils in Beijing. The flowers are red and the beans are dark purple. This kind of red lentil seems to be eaten by no one, just for viewing. I think this kind of lentil is unusually red and not as beautiful as purple flowers and white flowers.
