为时太晚

• One explanation for it is that during the times of arranged marriages , the bride ' s face was covered until the groom was committed to her at the ceremony so it would be too late for him to run off if he didn ' t like the look of her
  对此习俗的一个解释是，在包办婚姻的时代新郎以婚礼形式正式接受新娘之前，新娘的脸要被盖起来，这样一来，等到他看到她时，即便不喜欢她的模样，但已为时太晚了。
