As we walked up and down the alleys of not only vegetables, but fruit, meat, fish (including frogs and turtles) and poultry, one of our group asked how the people decide from which to buy, "They all have a lot of the same products," she commented. Our local guide and cooking teacher told us that she looks at the produce and buys whatever looks freshest. Some buy from friends out of loyalty.
Regardless of the village, town or city, there are vegetable markets all over China. Join me on a trip and check it out!
