One thing I wish you could get in China is "Gladware". It's made by the same American company that sells Glad Wrap and Glad Zip Lock bags here. It is a line of cheap, reusable, Tupperware-like containers. They come in various sizes and are optimized for people who regularly pack and transport homemade food. They make little ones that are good for lunch and big ones that are good for picnics. They work well in the microwave and are durable enough to use for months, or years. The key thing is that they are cheap enough that if you lose them, its not a major expense like Tupperware, or Rubbermaid.
The problem with most of the Chinese stuff I find is that these containers don't really seal well. The leak too easily.
