The difference between inheritance and continuation

Continue to use the past methods, systems, decrees, etc. The original meaning of "Yan" is to follow, and it is extended to follow, that is, to follow the previous methods, rules, styles, etc. , such as "follow" and "get used to each other"

"Continue" has the ambiguity of "delayed use", that is, it is not used within the prescribed time limit, and it can still be used or allowed to be used after this time limit.

I used to use "follow-up", but I still use it now. For example, use the century-old brand "Nancheng Heng Hotel". So the standard usage is "used". Cihai and Modern Chinese Dictionary only include "used".
