A few years ago, I took my family to visit Beihai and Fangcheng Port, thinking that I could go to Vietnam's small towns to have a look. But when we arrived at Dongxing Port, we came across that the port was being expanded and renovated, and the traffic was stopped! __________ No way, we can only turn around around around the port. Turning around, he came to a garden and saw the landmark. The boundary marker seems to be some years old. According to the inscriptions on it, we can see that this is the old boundary. It seems that the present boundary has been pushed out a little. There is also a border guard barracks in the distance of the boundary pillar. Many tourists are standing outside the barracks fence and curiously probing inside. I really don't know what to look at. My little fart boy even pretended to put up his toy telescope to look at it. Look at that solemn and unaware of the heavens and the earth. It's so amazing! But then I stopped it and took him out of the military zone.
