When they returned to their residence after dinner, everyone talked happily about the feelings of the day. Now they were exhausted, so they took an early rest so as to have good energy to welcome the activities of the next day. We got up at 6 o'clock and went to the second stop after breakfast. For some reason, perhaps without the support of the leaders, we stayed here for more than ten minutes and handed out some leaflets. The teacher decided to divide the troops into two routes: one to Yuanqu Village and the other to Guxin Village in Guxin Town. The driver left the first group in Yuanqu Village on the way, and our second group continued to go to Guxin Village. As it was launched yesterday, we all had experience and completed the task smoothly. When the two groups arrived together, it was already over 11 o'clock, and we took a bus to the school. After a night's rest, I also got up early on the third day and took a bus to Shenze County, Shijiazhuang City. This time it was also divided into two routes. The first group went to Greater Jia Cun and our second group went to Southwest Liucun. After obtaining the consent of the local leaders and the understanding and support of the masses, we carried out the activities. Everyone had the experience of the previous two days and was already quite skilled in the publicity and investigation work, so they completed the task smoothly.
The newspaper said: "The total number of cancer deaths in the United States showed a downward trend for the first time in 2005." "Cancer is a chronic disease that can be treated, controlled and even cured." In the past, it was believed that cancer would lead to death, and it would take less than three months. Now it is believed that cancer is a chronic disease that can be treated, and the treatment method will change with the change of understanding. The decline in the death rate of cancer patients in turn proves that this change of understanding is close to the right direction. Western medicine came from the West. At present, the number of cancer survivors in the United States is 1/29 of the total population, while that in Shanghai is only 1%, which is far from other places. This shows that Shanghai's understanding and treatment of cancer are still shrouded by the shadow of past mistakes. Many innocent lives still die under the wrong medical understanding and medical methods.
