First, don't go out alone.
I advise you not to go out alone. This is very dangerous for women. You should let your brother or your father go out with you, or you can be friends. I hope your friend is a man, because he will protect you when you meet a gangster in the car. Gangsters will not make a move when they see your company.
Second, go out with defensive tools.
Don't forget to bring defensive tools when you go out, such as pepper spray. When you meet a gangster, spray pepper spray on his eyes, and you run away immediately. Don't wear high heels when you go out, because you will run very slowly when you are in danger. When you meet a rogue who molests you, you should choose to get off at once and change to another car, but remember to get off at a crowded place. If you choose to get off at a remote place, you should.
Third, learn to fight to protect yourself.
If you have kung fu and know how to fight, then when you meet a rogue, you will knock him down in an instant and then run away immediately. Knowing kung fu is really a better way to protect yourself. I think, when your kung fu level is deep, even if there are five hooligans in front of you, you won't be afraid, so learning kung fu can not only keep fit, but also get yourself out of danger quickly. This is indeed a good thing.
Fourth, be a strong person.
You have to be a strong person, buy a car and drive to a place, so you don't have to squeeze the subway bus to work, and you won't be harassed by hooligans again. Try to start a business to make money. May you be independent, strong and beautiful. Come on!
