Problem description:

Come on! !

Analysis:

Yanzi, the word Ziyou, also known as Uncle, often knew each other in the Spring and Autumn Period. He went to Shandong to study under Confucius and listed four subjects. The only southerner among Confucius' 3,000 disciples was listed as one of the "seventy-two sages". Ranked ninth among the top ten disciples of Confucius, "South Teacher".

Born in Wudi, he studied under Confucius in Shandong as an adult. Judging from Yan Yan's 45 years younger than Confucius, he should be regarded as a student of Confucius in his later years.
