The explanation of "My sister's name is Lu Hua/My sister is beautiful" may be different. Some people understand that Lu Hua is a girl's name. She is as beautiful and pure as Lu Hua. Therefore, some people further think that this poem has the feelings of Haizi's Seeds of Love. This understanding is also possible. In a village where Lu Hua lives, it is normal for some people to name their daughter Lu Hua because of their love. I tend to understand that the poet Haizi regards reed as his sister, and in the pure and beautiful characteristics of reed, the guardian of the poet Haizi is a pure and beautiful heart of Haizi.
This poem is short, but beautiful.
