As the saying goes, "dogs don't take good barking as good, and people don't take good words as good." Although the truth of this sentence is deep, it is very shallow. Anyone with a little knowledge can understand the profound meaning of this sentence: dogs should not be good at barking, but should be good at loyalty; People don't regard good words as sages, but do things with sages. But what I want to say is not deep-seated "loyalty" and "hard work", but shallow "good barking" and "kind words"
