This morning, her son and daughter-in-law had an appointment to go home for breakfast. After waiting for a long time and seeing no one, Aunt Liu called the couple. As a result, both phones were turned off. Aunt Liu waited until more than ten o'clock. When the food was cold, she did not say anything about her son and daughter-in-law. Aunt Liu was a little panicked and hurried to her son's house. She pushed her son's door and found that the door was left unlocked. When she approached the door, she found no one in the living room. "What's the matter with you? Your cell phone is turned off!" Aunt Liu shouted loudly, but no one answered. She could only continue to walk to the bedroom. "What did I say you were doing?" Aunt Liu knocked on the bedroom door and asked, but no one answered. She pushed open the bedroom door and saw that the bed was clean and the couple was not at home. In addition, she did not find anything unusual at home. However, when she turned around and came out, the scene in the yard frightened her to disgrace. In the yard, the son's dog fell into a pool of blood. A blood hole was cut out of his head and thrown into the corner of the wall. The bricks beside him were covered with blood. Seeing that the ground was covered with blood, Aunt Liu collapsed with fear and called 110 to call the police.A few days before the fall of Nanjing, the Japanese naval aviation sank the US warship Panai in the Yangtze River. The incident caused quite a stir in the United States and angered the whole country. As the "Panai" was carrying a group of photographers and cameramans, the incident was recorded by video and then produced into a documentary by MGM, which was screened in the United States. In order to prevent the anti-Japanese sentiment in the United States from getting out of control and forcing the U.S. Government to intervene in the war against Japan too early, President Roosevelt ordered the key parts of the film to be cut off so that the fact that the Japanese army deliberately attacked could not be revealed. Even so, the screening of the film has completely reversed the American people's perception of Japan. The public opinion foundation for the United States to support China's resistance to Japan has begun to take shape. The war between Japan and the United States began with Pearl Harbor attack. As for the prelude, many historians believe that when the Panai was sunk, it was already opened. Japan has always insisted on this matter as a mistake. However, Aban entered the curtain and was close to everyone at the top of the Japanese army to expose Japanese lies with first-hand personal experience. The "Panai" incident occurred in the Yangtze River of China and sank a few days before the Nanjing Massacre. It played an important catalytic role in the evolution of the triangular relations between China, Japan and the United States. There are new writings on this matter in the United States at the age of 18. However, the study of Chinese historiography has been completely silent and has remained blank so far. Interestingly, Matsumoto's "Shanghai Times" briefly mentioned the Nanjing Massacre and simply avoided talking about it. Perhaps because the incident involved the darkest scar of the Japanese army, it was really difficult to deal with it properly. Aban's book shows all aspects of the incident to Chinese readers. One is fresh, the other is in-depth and comprehensive, and the reading results are more than general. Of course, about the surging wind and cloud in the United States 在家里是个甩手大爷，家务事从来不动一手指头。杨红英已经习惯了自己这操心受累的角色，但仍然免不了发两句牢骚。儿子洋洋从小就住在奶奶家，金老太太对孙子十分娇惯，弄得洋洋一身毛病，学习也不努力。Princess Pingyang and Emperor Wu of the Han Dynasty met Li Yannian while listening to the court band playing music.
