When looking at the present, it is advisable to learn from the past, as the present cannot be achieved without the past. From "Zengguang Xianwen".

The original meaning of this "Xian Wen" is: to observe today's things, we should learn from past history. If there was no past, then there would be no today. This "Xian Wen" enlightens us that only by paying attention to learning from historical experience and grasping the laws of the development of things can we seize opportunities, do a good job, and make a wealthy life.
