Vegetable producers sell their vegetables in baskets. They put their baskets on a cloth on the ground. Meat producers put their fresh meats on stone tables for marketing. The stone tables were built for this purpose some time in the past. Some producers sell animals to customers when the animals are still alive.
People can buy chicken when the chicken is alive, so it is very fresh.
Fruits and bread are also available at the market. This market field is just like a giant grocery store. My parents can make chicken wings exactly the same way in Canada as they did in China. The only thing that's different is that my parents used fresh chicken meat in China. I think because of this the chicken wings taste different in Canada.
