The original meaning of expanding data is to grasp the profound meaning and forget the words that express it; When the fish is caught, the fishing gear can be forgotten. It means that although writing and fishing gear are indispensable, they are only means after all, and it is more important to understand the spiritual essence and achieve the set goals.
In ancient times, a fisherman went to the river to fish. He threw the raft into the water and looked at the buoy intently. Finally, a red silver carp caught the raft. He was very happy to take off the fish, throw the raft aside and go home quickly to brag about his contribution. The wife said it was Sasakawa's credit and asked him where Sasakawa had gone. The fisherman remembered that he had forgotten to take Sasakawa home.
