Master of Stinginess

I heard of some variations of the same joke.

一个吝啬的人，想使自己变得更吝啬，便拜一位被称作“吝啬大师”的人为师傅。求见时，他带去两件礼物：一条纸剪的鱼；一瓶淡水，算是酒。可是老师不在家，师母出来接见。她知道那人是来学本领的，便叫婢女递上一只空杯，说：“请用茶。”又用两手合了一个圆圈模样，说：“请吃饼。”老师回来了，听了妻子款待学生的经过，急得顿了顿脚，说：“你太破费了！”又用手合了半个小圆圈，说：“半个饼就足够了！”

Once there was a very stingy person,he wanted to be even more stingy,so he became a disciple of a man who was nicknamed "Stingy Teacher."When he wanted to see the teacher,he brought two gifts with him: a paper fish;a bottle of water,which counted as wine.But the teacher wasn't at home,so his wife came to the door.She knew that the person came to learn skills,so she called a maid to throw an empty cup over,and said, "Please have some tea."and used her hands to form a circle,and said, "Please have some cake."The teacher came back,and heard of the incident of his wife giving the student a "feast,"and became hopping mad,and said, "You're such a money waster!"and used his hands to form a semicircle,and said, "Half a cake is enough!"
