Will it be bad for girls to work in hotels?

That's not necessarily true ... this is the dialectical relationship between internal and external causes in philosophy. Internal factors play a leading role, and external factors can only affect it. Can't decide. In other words, if this person's essence is bad, then no matter what the environment, he will become bad. If this person is good in nature and very determined in willpower, no matter how bad the environment is, he can't be shaken. But if the essence is good but not very firm and easy to shake, then he is likely to change because of the change of environment!
