I demand that there be examples of "the cost of youth" at any time and in any country.

Su Qin is from Luoyang. Luoyang was the capital of the Zhou Emperor at that time. He wants to make a difference. He once asked to see Zhou Tianzi, but there was no way to introduce him. In a rage, he sold his property and went to other countries to find a way out. But he ran for several years and didn't become an official. Later, I ran out of money and my clothes were worn out, so I had to go home. The family saw him wearing sandals and carrying a broken bag, looking like a mess. His parents scolded him severely; His wife sat on the loom knitting silk without even looking at him; He begged his sister-in-law to cook for him, but she ignored him and leaned down and walked away. Su Qin was greatly stimulated and determined to take a breath. Since then, he has been eager to learn and study Sun Tzu's Art of War every day until late at night. Sometimes I study until midnight, and when I am tired and sleepy, I prick my thigh with an awl. Although it is very painful, sometimes it is still bleeding, but when the spirit comes, I will continue reading. In this way, after more than a year of hard work, his knowledge is much richer than before.

Endure hardships to achieve some ambition.

In 496 BC, He Lv, the king of Wu, sent troops to attack the State of Yue, and was defeated by the State of Yue. He Lv was seriously injured and died. Two years later, He Lv's son, Fu Cha, led an army to attack the state of Yue, and Gou Jian, the king of Yue, was young, thinking that he could defeat Wu as long as he led the army. As a result, he refused to listen to the ministers and was afraid of persuading Yin, and was finally transferred to the State of Wu. In order to defend his country, he became a slave in the state of Wu and endured humiliation and served for the king of Wu for three years. This just let down the guard and sent him back to Yue.

In fact, Gou Jian did not give up revenge. On the surface, he obeyed the king of Wu, but secretly trained elite soldiers, strengthened political supervision and governance, and waited for an opportunity to fight back against Wu. Hardship can exercise the will, and ease will kill it. Gou Jian was afraid that he would covet the comfort in front of him and kill the will for revenge, so he arranged a hard living environment for himself. He sleeps at night without a mattress, just laying some firewood (called salary in ancient times) and hanging a gallbladder in the house. In order not to forget the shame of the past, he will taste the gallbladder from time to time.

In order to encourage the people to join the Queen and the people in the labor, Gou Jian made the State of Yue strong with the help of Vietnamese Qi Xin, and finally found the opportunity to destroy the State of Wu.

Su Xun, Su Xun, one of the eight masters in Tang and Song Dynasties, was bohemian and thought he was brilliant when he was young. They don't need to study, and they are young and energetic. They thought their works were quite excellent, but they didn't expect to drop out of the list the first time they saved the exam. Since then, all his previous works have been burned. He studied hard for ten years and finally became a generation.

Jacky Cheung, after the success of her solo concert in the Red Pavilion at first, lost her way because of her youthful spirit. 1987, the sales of his new album plummeted without winning the prize. At this time, he began to drink heavily, and the media repeatedly reported news against him. This state continued until 1989. There are different opinions about his low tide. Judging from the information he has been interviewed by the media in recent years, it is precisely because of his youthful spirit that he quickly lost his way after becoming famous overnight and was pessimistic about the future, which directly led to his self-abandonment in his career. From 1989 to 1990, Alan Tam and Leslie Cheung successively withdrew from the Hong Kong Music Awards ceremony. Jacky Cheung seized the opportunity to become one of the lead singers of Polaroid Records Company, and released the record "I only want to love one person in my life" at 1990, which once again attracted the attention of the music circle. His songs returned to several major music charts in Hong Kong, and caused a sensation at several major music awards ceremonies in the same year, successfully inheriting the award-winning status of his predecessor Alan Tam in Polaroid Records.
