❍ 只愿主人当那醉余睡醒之时，或避事消愁之际，把此一玩，不但是～，却也省了些寿命筋力，不更去谋虚逐妾了。(《红楼梦》3) My only wish is that men in the world below may sometimes pick up this tale when they are recovering from sleep or drunkenness,or when they wish to escape from business worries or a fit of the dumps,and in doing so find not only mental refreshment but even perhaps,if they will heed its lesson and abandon their vain and frivolous pursuits,some small arrest in the deterioration of their vital forces.
