If you go to Yanqing, salty egg, the local specialty, is one thing you won't miss! It's made of egg of duck and fountain and salt. It's just sooo delicious! it's my favorite. That's 100% flavor of countryside. Just cook yourself a rice soup then eat it with the salty egg, you'll see why I love it so much:) Liulaoya is the local brand of salty egg that you can trust.
