If you're not known enough about China, you should not claim "That is a lot of money for a working class Chinese person." Actually, 19 yuan is ignorable for working class Chinese person. You can only buy about 1 hamburger in McDonalds, or buy 0.5 kilogram pork, or buy a bowl of noodle by using 19 yuan (delicious noodle costs at least double). China has changed a lot. If you have time, you can visit Shanghai, Beijing, and many other cities. You'll find they're all modern and safe cities, and you'll find your claim is totally wrong.
