《孟子·尽心章句上·第四十六节》
不能服三年之丧，而对于三个月、五个月的丧服却很明察；大吃猛喝，而又考究不损伤牙齿的食物的人，这就称之为不识大体。 
不能三年之丧，而缌小功之察；放饭流歠，而问无齿决，是之谓不知务。 
If you cannot serve three years of mourning, but are very observant of three months and five months of mourning; if you eat and drink heavily, but are particular about not damaging your teeth, then you are called a person who does not understand the general principles.
