Ice lotus: Ice lotus belongs to Nymphaeaceae, a thousand-petal lotus in the lotus, which is a miracle of double flowering in the plant world. Bindilian is a variety of lotus. It has two flowers on a stem, and each flower has its own pedicel. Pedicels are connected together on the stem, so some people call it lotus head. Although it can be found in various ancient medical books, some people suspect that it is a fiction of literati.
For example, there is a sentence in Yin's "Northbound Miscellaneous Poems": Pointing at the moon is not for everyone, and the green pool seals the sky. Because the ice-washed lotus is produced in the lotus pond and is open in clean and unpolluted pool water, people praise its noble character by "getting out of the mud without dyeing".
