Are you talking about small walnuts in Shanghai? If there is, you can't buy it in the flower and bird market, Sanqiao and Wulichong. Go to Wal-Mart, Beijing Hualian and Zhengxin Street wholesale markets to buy them. If there is, I will buy something to eat occasionally! If it's not a small walnut in Shanghai and Zhejiang, you can buy it everywhere! Most of the flowers and birds sold in the market are local walnuts or Guizhou walnuts, such as Hezhang walnuts!
