We're here at Mount Huangshan! The clouds (look) amazing. It (feel) like a magical place. The trees and rocks (look) like a part of a painting.
We're at a rest area now. Climbing (be) hard, but we're (make) good progress. Although the weather is bad, many people here are still in high spirits. I (not think) my brother Peter (enjoy) the experience very much. So I (encourage) him.
The sun (shine) through the clouds! It (be) a lovely sight. I (be) so glad we're here at Bright Peak.

Climbing (be) tiring, my shoes (be) all wet and dirty too. There (be) many other tourists at this rest area, but they (not seem) tired at all. Instead, they (talk) and (laugh). My sister Helen (be) also in high spirits.
We're here at Bright Peak. Mount Huangshan (be) beautiful in the sunlight. I (be) tired and hungry, but it (feel) good to be at the top.
