A farmer in Zibo, Shandong province, sells cooked eggs for 0.7 yuan apiece. But Wu Shengying`s eggs aren`t cooked in the usual way - Wu bakes his eggs in an oven. He said it`s easier to control the temperature and cooking time of an oven compared with microwaves or charcoal stoves.

Wu makes 0.2 yuan in profit on each baked egg. He has applied for a patent on his cooking method and hopes to bring in 100,000 yuan a year through the patent.
