Lin Xia, 28 years old, is working in Shanghai for the 6th year as a cost clerk. Working overtime, staying up all night, and having stomach problems are all the same. At age 28, she landed herself in the emergency room. Hanging on the water, she figured it out: quit. The deposit is 184,000 yuan, which is enough for her to live in this city for two years. She quit the rental house group and rented a small shop. Get up at four in the morning and bake bread. On the first day, it was burnt. The next day, it was still mushy. On the third day, a customer came to the store - he didn't even have time to take off his white coat, and his eyes were blue. He bought the cheapest bread and asked in a hoarse voice, "Can you give me a cup of hot water?" Later, Lin Xia found out that his name was Wen Xu, an emergency doctor who had been working the night shift for ten years. She said: "You must have a good breakfast." He said: "You must have a reason to get up at dawn." Later, the whole alley knew that at four o'clock in the morning, as soon as the lights in the bakery turned on, it was time for Dr. Wen to come after the night shift.
