The old saying "three rams bring bliss" is connected with the fourth day, which says that by making a good beginning a happy end comes.
初四则和俗语“三羊开泰”有关，意思是岁首吉利就预示着岁末幸福。
According to folklore, it is also the day to welcome back the Kitchen God. On this day, the Kitchen God would check the household and therefore people should not leave home.
民间还传说这一日是迎回灶神的日子。这一天灶神会清点每家的人数，所以切忌外出离家。
