Why taoli?

桃李 táolǐ"Peach and plum trees", a name that evokes two well-known Chinese sayings.

桃李不言，下自成蹊"Peach and plum trees do not speak, yet a path forms beneath them." The historian Sima Qian quoted this proverb about General Li Guang, a man of few words whose soldiers loved him and gladly followed him.

桃李满天下"Peach and plum trees cover the earth." The trees are a teacher's students.
