There is a saying: "Spike always bow its head, while barnyard grass holds its head up. "The more mature and full the spikes get, the lower their heads may droop. Only that fruit-less and empty barnyard grass will hold the head high. In our life, we should learn to keep appropriate low profile at appropriate time. This is by no means cowardice and retreat, but an intelligent way of life; it implies great wisdom of and large state of life. Often times, we bend our heads to see the true beauty of life.
