Not to do anything, this is the principle for both the Academy and Taoism at the moment. The Drunkard was drinking at a small restaurant while looking to the east. The Eldest Brother was standing by the cliff and also staring at the east. They were both aware of each other's thoughts, as they both wanted to visit the Song but could not. Because going would create trouble.
They could not leave the small restaurant. Instead they could only keep drinking and looking afar. It became boring after a long while hence they had to find some topic to kill time.
