In the "Compendium of Materia Medica", there are records: "The peas are planted in the West Lake. There are many northern soils here. In September, the seedlings are weak and vine-like. They are necessary, and the leaves are like eucalyptus leaves. They are opposite each other. They are edible when tender."
The peas are placed in a drain basket and washed several times a day. After germination, they can be taken for consumption.
