Can anyone tell me the difference between "old" and "old"? Details! Thanks!

Lao generally describes people and things, meaning that time lasts for a long time. Such as old man, old person; old tree, old house; (old aunt and old sister of Northeastern people refer to small ones, which is another matter) are also used to express abstract things, such as maturity and aging, but most of them are caused by time; sometimes It has nothing to do with time, like my wife.

Old generally describes items, meaning they last a long time. Such as old TVs, old tables, etc.; it is also used to express abstract things, such as old feelings and old things, which are mostly related to the long history of time.

Don’t tell me, the answer to this kind of question is much more difficult than doing a math problem. I can’t say for sure, it’s for reference only.
