both the branches and leaves spread out
Zhiye Fusu is a Chinese idiom. Its pinyin is zh ī y è f ú s ū, which means that the branches and leaves are luxuriant and dense. From Strange Tales of a Lonely Studio - planting pears.
The idiom comes from Pu Songling's Liaozhaizhiyi · planting pear in the Qing Dynasty: "when you see thousands of eyes, you can see that some hooks sprout and gradually grow up; when you grow up in Russia, the branches and leaves support each other, and suddenly blossom and become solid, and the trees are full of fragrance."
