I've received this Dumpling shaped-postcard from Jin Hua of Xi-an , China.
Dumpling (or 饺子 Jiao zi) is a traditional Chinese food. It's one of the most widely loved foods in northern China, as it's popular in cold weather. The dumplings can be boiled in soup / steamed / fried. The dumplings can be filled / stuffed with anything from meat, vegetable to fruit.
What tempting me most about dumpling is eating with the dipping sauce.
My favorite combination ~~ " ginger + vinegar + soy sauce + fish sauce "
