1应当定期理发。根据头发生长的一般规律,常人在每半个月左右理一次头发是最为恰当的。至少,每次理发的时间隔也不宜长于一个月。如果经年累月拒绝理发,个人的形象必将令人惨不忍睹。有些特殊的时候,例如参加重要的庆典、宴会时,为显示自己郑重其事,特意临时再理一次发,也是非常必要的。 1 should be regularly hairdressing. According to the general rule of hair growth, it is most appropriate for ordinary people to manage hair once every two weeks or so. At least, the time interval between each haircut should not be longer than a month. If after years of refusal haircut, the image of the individual will certainly be appalling. In special occasions, such as attending important ceremonies and banquets, it is also necessary to show one’s solemnity once and for all.
