give up halfway半途而废
During the Warring States Period (475-221BC), there was a man called Yue Yangzi in State Wei.
A year later, he came back home suddenly. "Why have you returned?" asked his wife in surprise, "You've only spent one year studying with scholars."
"I come back because I missed you very much."
Without saying anything, his wife took a pair of scissors and went to the loom at which she had worked.
Pointing at the half done brocade, she proclaimed : "This brocade is woven from the finest silk.I wove one strand after another to produce the brocade. Now if I cut it, all my previous work will be wasted. It's the same with your studies. You can acquire knowledge only through diligence. Now, you've given up halfway. Isn't it the same as cutting the brocade on the loom?"
Yue Yangzi was moved by what she said. He again left home to visit scholars. Several years later he became a knowledgable man.
英文中“半途而废 ”可以用“give up halfway”来表达，意思就是“ 中途放弃”。
