Spring is coming to us with the warm weather and the signals of spring are the buds sprouting on the withered branches, the new green in the withered grass, and the warm wind in the early spring, which quietly bring spring and vitality to the world.

At this time, the sky is blue and the water is green on the bank of the Yellow River, the migratory birds are free to look for food and play in the water, the tourists are leisurely walking on the park path and the corridor pavilion is accompanied by melodious music. The children are running heartily in the Baihe Square, and the colorful kites are flying in the air with the spring breeze. The old Lanzhou city is full of spring scenery, vitality and warmth.
