The Mainland delegation of the Civil and Social Development Section of Hong Kong Middle School Students will set out from the first batch of schools as soon as April. Teachers and students responded positively. According to the latest data released by Cai Ruolin, the Secretary of the Hong Kong Education Bureau, more than 400 schools have registered by August. According to the Hong Kong Star Island Daily website on March 12, Cai Ruolin revealed when attending the event on the 11th that the first mainland delegation of the high school citizenship course will leave on April 3, with 250 students participating. Cai Ruolin revealed that the itinerary of the first batch of students who went north for investigation has been determined, and there are many highlights in the relevant arrangements. For example, one of the tours of the delegation is to Yongqingfang, a historical and cultural district in Guangzhou. Next to it is a famous middle school in Guangzhou. The delegation will not only understand the conservation of Guangzhou's historical and cultural heritage, but also interact with local students and watch their Cantonese opera performances. According to statistics, more than 6000 students and more than 60 schools signed up in the whole April. At that time, it is estimated that there will be about 100 people in a group, with a total of more than 60 groups going north for investigation. Cai Ruolin said that more than 160 schools and about 16000 students will participate by May; Between June and August, more than 200 schools have signed up. Many students have applied for a homecoming permit before their departure. Mei Zhiye, the principal of Liu Yongsheng Middle School of the Chinese Missionary Association, said that all the sophomore students of the school have applied for a homecoming permit and will receive the certificate successively from this week. It is estimated that they will leave for Huizhou, Guangdong Province, in May to participate in a two-day inspection mission. Wu Huanjie, the principal of Peiqiao Middle School, said that about 30 senior two students in the school had not yet completed their certificates, and they would do so collectively at the end of this month. The tour is designed for one to three days, so that students can understand the latest development, culture and history of the country during the tour, which is very helpful for learning. In recent days, Cai Ruolin, accompanied by Li Meichang, Permanent Secretary-General, Chen Muyan, Deputy Secretary-General, and more than 20 representatives of the education sector, has visited several civic science research missions in Shenzhen and Guangzhou. Accompanied by Shu Gangbo, Deputy Director of the Hong Kong, Macao and Taiwan Office of the Ministry of Education of the People's Republic of China, she has visited the Shenzhen Qianhai International Convention Center, Qianhai Shenzhen-Hong Kong Youth Dream Workshop, and then transferred to Guangzhou. She has visited the Pearl Bay Development and Exhibition Center in Nansha District The Museum of Cantonese Opera Art at Chen Family Temple and Yongqing Square. Cai Ruolin stressed that the purpose of the investigation group is not tourism, and the activity design should include elements that let students think and interact. In order to prevent students from "looking around the bush", the Hong Kong Education Bureau will also promote school teachers to come to "explore the way", and the subsequent student inspection activities will also add interactive links instead of "one-way reception". In fact, some teachers from Hong Kong secondary schools have visited the mainland to experience the journey. Wu Huanjie said, "We once considered the one-day tour in Zhuhai. A teacher visited the local area, but found that the drive was too long for us.". At present, the secondary school plans to visit Shenzhen to let students experience the "1 hour life circle in Dawan District". Wu Huanjie stressed that the mission is part of the learning experience. "As a teacher in charge of the mission, we should prepare and understand the specific learning focus of the trip in advance and how to guide students to think". Taking the aerospace science popularization education base on the trip as an example, he said, "Although there is information online, will there be experience content in the trip, such as letting students try on aerospace suits
