The whole walk is still quite leg-consuming. I look at the three countries at a glance. The left is Mongolia and the right is Russia. The door is very spectacular. It is the fifth generation of the door. Standing here, my heart can't be proud of the colorful Matryoshka Square. I walk and watch, I don't feel tired, I just feel that my eyes are not enough. Color application is too bold, too dazzling, Manzhouli, full of vitality, worth walking!
