The sound that is still ringing in your ears means that time has passed, and the words you said still seem to be ringing in your ears. The rich of the country should not forget the old days. The poor means that the rich are rich, and don’t forget the greed. A famous saying by Mr. Lu Xun is heard loudly and loudly. The rich man of a country should never forget his old poverty. Dare to speak up and be upright. Don't break your waist for five meters.
