I am in this process have had the access to gain a large number of first-hand scientific research materials， withstood the thrilling test. There have been relaxed and happy heroic， but also experience of luck in the dangerous environment. In the field expedition， difficulties and dangers are often unexpected， sudden. Any lack of contingency of wisdom and ability will lead to the helpless situation， paying a high price and even life.
　　During my travel all over the world， I have broaden the horizons， accumulated experience， honed the will， enhanced the body. A few days ago， I was able to work in Tibet， living a few days four or five kilometers on the plateau. I am deeply attracted by the charm of nature， and grateful for nature’s blessings！ Only personally embrace and be embraced by the nature can we truly feel the mystery of it.
