Confucius said: “None those who accompanied me in Chen and Cai are still with me.”
Book 11 features a wealth of comments from Confucius about his disciples. In this chapter, Confucius is referring to an incident that occurred in 489 BCE when he and some of his disciples including Zilu, Zigong, and Yan Hui nearly starved to death on the road from the state of Chen to the state of Cai after being surrounded by some angry locals for seven days.
By the time Confucius returned to his home state of Lu in around 483 BC, Yan Hui was already dead and the others had moved on to other posts. Hence his lament that none of them were still with him.
