Last week my parents and I took a two-day trip to Emei Mountain in Sichuan.Like everyone knows, it's famous mountain with all kinds of plants and animals.The weather was fine. It was about noon we arrived at the foot of the mountain.The three of them were very excited. As we climbed the mountain, we fed monkeys,visiting temples and told stories. On the way up I was busy take pictures since the scenery was so beautiful. The time passes quickly.Evening came. We spent the night in a hotel at the top of the mountain. The food was expensive and the service was  good. I was so tiring that I fell asleep at the moment my head touched the pillow.
