This is a proverb of China's traditional wisdom, which means: Don't cling to material and self, put everything down, and don't take gold, silver and jewelry too seriously. We should keep our responsibilities in a narrow space, but we should also be vigilant to prevent danger. Don't be afraid to explore the world because of fear, but bravely step out of your comfort zone and have the courage and courage to venture into the world. The meaning of this sentence is to let us put down ourselves, put down the pursuit of material things, keep inner peace and clarity, bravely explore the unknown world, and pursue inner peace and freedom.
