The object of "Yu" is definitely inseparable from the main purpose of this hexagram, that is, the captured prisoners of war. The meaning of "Yu, Ji" is that you must be on guard against the captives to ensure that they are safe. The straightforward explanation is that you must be wary of others, especially those who have conflicts of interest with you.
The word "Yan" here means peace and ease. The word "Yan" in "Zizhi Yanju" in "The Analects" has this meaning. "If you have it, you won't be swallowed up." Since he is a captured person who has been conquered, wanting to ensure that he is of the same mind and heart as himself is probably a bit taken for granted and too idealistic. When the people under the rule are not united in their thinking and always have other ideas of one kind or another, there will be hidden worries about the overall harmony and stability, and it will be impossible to ensure long-term security and stability. This is the meaning of "there is no need to swallow".
As a manager, you must be able to accurately grasp the unstable factors that exist in your team. As for how to prevent the risks caused by these unstable factors, you need to have comprehensive risk identification and management and control capabilities. This is the connotation of the word "Yu" in practice.
