Mountain introduction: A huge word "dream" on Tongtian Peak makes people imagine endlessly. This character was written by Ma Siji, a famous Chinese artist. In order to carve this 2.4-meter-high and 2-meter-wide character into the cliff, the staff spent half a month. It took more than 30 workers three days to transport 8 tons of scaffolding steel pipes to the foot of the cliff, and the carving process took another nine days.
