Yes but Guangzhou has got some of the worst crime in China, (not including all the pickpockets). Every place you will live in China has it's drawbacks, you just have to ask yourself what exactly is most important to you, what are your priorities? Then you'll be able to know if you can live in a less developed place, or if you can tolerate one that can be as dangerous as Guangzhou because development is what you really want. Also, some people are more adaptable then others, something you need to keep in mind, as well as whether or not you are one of those people.
