National Respect The U.S. Flag Code addresses hat removal, stating that during the national anthem, when the American Flag is displayed, "men not in uniform should remove their headdress with their right hand and hold it at the left shoulder, the hand being over the heart."

MLB比赛前奏国歌时，球员们脱帽置于左胸处。

还有一种情况提醒大家是必须要脱帽的。在烈士陵园、纪念碑或者公墓鞠躬时候帽子要提前脱下来。显然大家已经都有这样的认知和素质。

还有几天就要到国庆假期了。提前祝大家国庆假期愉快！
