In our first three years in Shanghai, we bought our groceries from Carrefour in Gubei which was a 30 minutes taxi ride away. After that, we bought everything from our neighbourhood wet market which was 15 minutes away by walking. And I always bought my eggs from the wet market from this mate here. He was there most of the time and sometimes his wife will be there or his son and I always had a short conversation with them. They were always amused to see a foreigner coming to their shop to buy eggs regularly. The only regret I have is that I had never actually asked him what’s the difference between these eggs.
