What's the difference between the glorious isolation of Britain and the closed door of the Qing Dynasty?

China's humiliating modern history began in the Qing Dynasty, largely because of its backwardness. The rulers of the Qing dynasty were very arrogant, thinking that they were already very powerful, and there was no need to communicate with other countries, and they closed their doors to the outside world, which eventually led to the backwardness of the Qing dynasty and western countries and eventually became colonies.

Then Britain has been gloriously isolated in history, so why didn't Britain end up in such a miserable situation? In fact, there is an essential difference between the two.

Britain's glorious isolation is not completely isolated from other countries. It still does business and contacts with other countries, but it does not establish friendly alliances with any country, that is, it does not form small groups.

This is equivalent to two different people. A person just stays at home most of the time, but still keeps in touch with the outside world and goes to work as usual, but never socializes and drinks at the same time. But there is another person who stays at home all day. He doesn't even have a wireless network at home, and he has nothing to do with playing stand-alone games. He thinks his life is the most exciting.
