There are endless conquests across the four continents. Those who are ambitious have a commanding view of the world, those who frequently conspire are just trying to gain fame and reputation, and those who practice hard and ask questions are frustrated and lonely, and their families and people are ruined. Ask about other people's hearts and ask about your own hearts. If you don't have happiness or shame, you won't be able to cultivate to perfection. Seeking others and seeking oneself, without love and ruthlessness, there is no end in sight. For the common people and the family business, there is no morality and no justice, and there is no time to live in it. In the world of chess, who is the player and who is the pawn.
