Many times, we have to live with fatigue and disguise. Perhaps only at home can we completely relax, but unfortunately we have less and less time at home and more and more time in society. I am often moved to tears by the ancient man named Wei Sheng. "Wei Sheng made a date with a woman, but she didn't come in three days. When there was a flood, Wei Sheng hugged the pillar and died." Wei Sheng was such a lovely and persistent gentleman. For that agreement that may not be important, and to keep the contract written to him deep in his heart, he even used his life to defend it heroically. I saw two shining words in him - integrity.
