Zi Collection, Page Position: Upper Radical: Lid (tóu) Entry: Da Kangxi Stroke Count: 4 Page 88, Entry 05 According to the Tang Rhyme (Tangyun), pronounced ta. In the Commentary on the Analysis of Characters as Explicating Writing (Shuowen Zijian), it is noted that the original form was Da. It was pronounced with the same sound as the character for big. When positioned at the top, it is written as big; when positioned at the bottom, it is written as Da. Mr. Xu erroneously read the sound as he, and further changed the pronunciation to ta, classifying it under the entering tone, which is an error.
