[Collection of Explanations] Cangqi stated: Zhu Zi (Acorn-like nuts from Quercus species) grow in the Jiangnan region. The bark and tree resemble chestnut trees; they do not shed leaves in winter; the fruits are smaller than acorns.
Ying stated: There are two types of Zhu Zi: bitter and sweet. Processed into flour or cakes, the brown variety tastes very good.
Li Shizhen stated: Zhu Zi grows in valleys everywhere. The trees can be several people wide in girth and two to three zhang high. The leaves are large like chestnut leaves, slightly pointed at the tip, dense, hard, glossy, with sharp serrated edges, remaining evergreen through winter. In March and April, white flowers bloom in spikes, resembling chestnut flowers. The fruits are as large as oak nuts, enclosed in small husks that split after frost, causing the nuts to fall. The nuts are round, brown, and pointed, about the size of Bodhi seeds. The inner kernel resembles apricot kernels; raw consumption is bitter and astringent, but boiled or roasted, they become sweet. They can also be ground into flour. Sweet Zhu Zi has small grains and fine white wood grain, commonly known as Mian Zhu (Flour Zhu). Bitter Zhu Zi has large grains and coarse red wood grain, commonly known as Xue Zhu (Blood Zhu). Those with black color are called Tie Zhu (Iron Zhu). Note: *Shan Hai Jing* states: "There is a tree on the front mountain, named Zhu." Guo Pu commented: "Zhu Zi resembles Zuo Zi (nuts from Quercus variabilis), is edible, and is harvested in winter." The wood is used for house pillars and coffins because it resists decay.
