I am currently in Chengdu and am willing to see Emei Shan or Jiuzhaigou, but not both. I also don't want to spend more than 2 days in either place.
I do not know much about Chinese history and have already seen a few temples from my visits to Japan and China. So will Emei Shan not be very exciting because of that? However, I am interested in seeing the giant Buddha statue in Leshan
