Is it enough to shoot Gongga Snow Mountain 120 focal section?

Not enough. It takes more than 200mm telephoto to shoot Gongga Snow Mountain, and the telephoto section above 200mm can shoot good results, but the 120 focal section is not up to standard and is not enough. Gongga Mountain is the main peak of Daxue Mountain, surrounded by 45 peaks with an altitude of more than 6000 meters. The main peak stands at the top of the peaks, with an altitude of 7556 meters, which is 6000 meters higher than the Dadu River in the east. It is the highest peak in Sichuan Province, known as the "King of Shu" and a national-level scenic spot.
