Wu Collection, Upper Volume Radical: Piece of cloth (pǐ) Page 768, Entry 02 Pronounced zhi (falling tone). Meaning to stop or be obstructed. In the Explaining Graphs and Analyzing Characters (Shuowen Jiezi), it is interpreted as being obstructed and unable to move forward, referring to a person who wishes to leave but is prevented. It also carries the meaning of stumbling or tripping. The Erh-ya (Erya), in its explanation of words, states that this term refers to falling forward. The Book of Odes (Shijing) writes: The wolf treads upon its dewlap, and retreats, it trips over its tail. The Commentary (Zhuan) explains that this term means to trip; the old wolf has a dewlap that it treads upon when moving forward, and it trips over its tail when retreating. The Sub-commentary (Shu) further explains that tripping over the tail when retreating refers to stumbling and falling upon the tail. Additionally, in the Broad Rhymes (Guangyun) it is pronounced du ji (falling tone), and in the Collected Rhymes (Jiyun), the Rhyme Assembly (Yunhui), and the Correct Rhymes (Zhengyun) it is pronounced ding ji (falling tone); the meaning is the same as the character for stalk or stem (di). The Erh-ya (Erya), in its explanation of trees, records that for dates and plums, one must remove the stalk. The Sub-commentary (Shu) explains that when processing dates and plums, one must remove the stalk, which is the fruit stem. The Book of Rites (Liji) records: When peeling a melon for the Son of Heaven, it should be cut into four pieces and covered with fine hemp cloth. When peeling a melon for a feudal lord, it should be cut into two pieces and covered with coarse hemp cloth. When peeling for a grand master, it should simply be covered. When peeling for a scholar, the stem should be removed. The Sub-commentary (Shu) explains that this term refers to the removal of the part where the flower stem was attached.
