Yu Juan of Fudan University wrote a diary for more than a year after she was diagnosed with breast cancer in December 29, in which she reflected on the details of her life and left a final famous saying: "At the critical point of life and death, you will find that any overtime work (staying up late for a long time equals chronic suicide), giving yourself too much pressure and the need to buy a house and a car are all floating clouds. If you have time, spend time with your children, buy a pair of shoes for your parents with the money for buying a car, and don't try your best to change a big house. With the people you love, it is warm to live in a humble abode.
