"Five-son Examination of Universities" comes from The Biography of Dou E's Injustice in Song Dynasty. It can be used as a blessing or auspicious language for marriage, and it is also an idiom to describe the secular pursuit of material satisfaction. Now, the "five sons" among the "five sons" are endowed with the meaning of house, car, ticket, wife and son, and a life with "five sons" is complete.
"Five sons" in the idiom "Five sons passed the exam" actually refers to five sons, and "passing the exam" means that all five sons have passed the exam. The story happened in the Five Dynasties and Ten Kingdoms period. Dou of Yanshan was originally an ignorant person. Later, he turned back to the prodigal son and trained all five sons as talents, all of whom graduated from this subject.
