Where did Yang Yanjing guard the border in Song Dynasty?

Han Xiao's little fresh meat boyfriend lives in the easternmost part of the island, and the fate starts from Dongqiao.

On the first day of last year, I had a bad idea. I wanted to watch the sunrise, so I dragged Han Xiao and walked to Dongqiao at three o'clock in the middle of the night. I was sleepy and wrapped in the pajamas of the same kitty cat. Although it is midnight, it is not quiet on the island. There are domestic cats on the roof, unknown insects are noisy in the passing flower beds, and the lights on the bridge say hello in the farthest place. Han provided and I walked slowly, not afraid of where the puppy would come from.
