Introduction to water tracing: Water tracing is an adventure sport between the upstream and downstream of a canyon stream, overcoming various obstacles in the terrain, and reaching the top of the mountain without accessing the source of water. River tracing is extremely challenging. Those who trace the river need to challenge rapids, shoals, deep pools and waterfalls to overcome difficulties and obstacles. It requires close cooperation among companions to complete the difficult climb. It is a test for the tracer and an achievement. Believe in yourself and your companions, and you will be satisfied after enduring the hardships. After fighting with the canyon streams, you will be intoxicated by the blue sky and clear water, alternating between passion and tranquility.
