Travelers have no boundaries. I followed the rut of history, followed the footsteps of history, and went upstream to find the glorious figure of my ancestors in the past.

Now we are following the footsteps of history, inheriting the fine traditions of our predecessors and dedicating our most youthful years.

There are still many records of nature on the earth. Understanding these records can not only "increase knowledge", but also "trace the historical footprint", develop underground resources and serve mankind.

Let's follow the footsteps of history and interpret the long civilization left by our ancestors.
