Zi Collection, Page Position: Upper Radical: Bird (niǎo) Page 1350, Entry 07 Pronounced di (falling tone). A type of bird. The "Classic of Mountains and Seas (Shanhaijing)" records that Ji Valley on Mount Shou has many niǎo birds. The "Commentary" states its pronunciation is like the "ti" in "qian ti" (qian ti). "Ti" is pronounced "di". Also, the "Guangyun" and "Jiyun" use the fanqie of "tu" and "gai" to indicate pronunciation, which is pronounced quan (falling tone). The niǎo bird resembles a bird, has three eyes, and has ears. Note: The character niǎo is composed of "bird" and "big". The character "big" originally had two pronunciations, "dai" and "di". The "Zi Hui" classified it as four strokes and changed "big" to "quan", with the pronunciation noted as "di". This error is very obvious. It is likely that the thing recorded in "Yupian" and "Classic of Mountains and Seas (Shanhaijing)" is the same kind of creature but has two pronunciations.
