This is a place where adults and children are worth coming to learn. The prophecy of a generation of arrogance is the only place to commemorate heroes. From 1940 to now, 75 years ago, it has been overhauled repeatedly, to the current situation, and I have been to the grassland. I must come here. The war was not easy, the endless grassland, There is no place to hide, lack of water and food, can open this territory, it is not easy! Let's miss the hero!
