Introduction to Xiluo Niuchang: Xiluo Niuchang is 3100 meters above sea level. Here you can look up and see Xiannairi, the first sacred peak of Gongga Risong and Gonbu. Under the blue sky, the white snow peaks of Xiannairi stand majestically in the vast sea of ​​​​forests, shining with silver light. Continue uphill for 2 hours to reach Zhazuo Yongyu (Niujiaogou), where there are dense forests and gurgling streams.
