Today, I went to a temple and signed a sign. Who can help me explain what the words on this sign mean?

This sentence is the number of rivers in the 64 hexagrams of the lunar calendar. Dan decreed that since the world, the situation will meet. Four strategies: including, no blame, no reputation. In ancient times, it was ordered by the emperor as a "imperial edict", and the purple imperial edict mostly referred to the champion stick or the official imperial edict. This sign is the sign at the top. To put it bluntly, it is a down-to-earth officer. When the situation changes, you can soar to the top, achieve great things or make a fortune. ..... accurate interpretation, hope to adopt.
