Xindu bridge! Photographer's paradise! The Tibetan people also call it Eastern Russia, with an altitude of about 3300 and a plateau mountainous climate. I went there once in October and once again in November, but the feelings of the two times are quite different. In October, the green leaves, the green mountains, the golden barley, the green and the yellow form a sharp contrast! ____________ In November, poplars stand tall and erect, showing off their unique golden yellow in the autumn wind and autumn sun. Groups of yaks and goats embellished in pastoral pictures of New Duqiao add a lot of vividness. The temperature difference between morning and evening in Xindu Bridge is quite large. Because of the strong ultraviolet radiation and the warmth during the day, clothes must be added at night. Students with poor physical quality must prepare more clothes.
