CCTV News:At the same time of teaching in space, China Science and Technology Museum organized a unique "second classroom" science popularization activity for space teaching offline.

On the afternoon of October 12th, the theme was "Hello, Miracle Palace! Earth! The "Second Classroom" popular science activity of space teaching was held in China Science and Technology Museum. Yang Liwei, the first astronaut in China, and experts in aerospace, physics, biology and other fields led young people to feel the great difference between heaven and earth and understand the important scientific significance of China Space Station as a national space laboratory through comparative experiments and multi-dimensional experiences.

China, deputy chief designer of China’s manned spaceflight project, first astronaut Yang Liwei:Space flight itself is a process of exploration. Through some of our work, more children can be involved, which is a very good inspiration for their future growth, especially for entering the society in the future.

The teenagers who participated in the activities watched the live broadcast of space lectures. Astronauts and experts from various fields interacted with the students to answer questions, interpret experimental phenomena and extend knowledge explanation. Various popular science contents planted scientific seeds in the hearts of students.

Student:I especially want to know a lot of new knowledge, because I want to be an astronaut when I grow up.

Student:I want to be a scientist when I grow up.

Qian Yan, Deputy Director of Party Committee Secretary of China Science and Technology Museum:China Science and Technology Museum and Manned Space Office jointly built the Science and Technology Experience Base of Space Station. In the future, relying on such bases, we will continue to lead the national science and technology museums to extensively carry out space science popularization activities and inspire more young people to participate in science popularization activities.

The selection of the fourth batch of preparatory astronauts in China has been started recently. During the activity, Yang Liwei also introduced the relevant details of astronaut selection.

China, deputy chief designer of China’s manned spaceflight project, first astronaut Yang Liwei:At present, we have probably divided some areas, such as some universities and research institutes, including some scientific research institutions and some pilots of the army. With the advancement of our project, more people may participate, which is also an inevitable development of the project.

　　CCTV News:At present, winter vegetables are listed one after another. All localities should do a good job in ensuring the supply of vegetables in winter, keep the "vegetable basket" of the masses, and ensure sufficient supply of vegetables and stable prices.

　　According to the vegetable production information dispatch of the Ministry of Agriculture and Rural Affairs, at present, the vegetable field area in China is 88.48 million mu, an increase of 1.15 million mu year-on-year; In late November, the output was 29.61 million tons, an increase of 750,000 tons.

　　Shenxian county is an important vegetable planting area in the north of the Yangtze River, and the local annual vegetable output reaches more than 5 million tons. The reporter saw in the agricultural products trading market in Shilipu Town that at dawn, local vegetable farmers came to the vegetable trading market early to sell all kinds of vegetables just picked.

　　At present, in the demonstration industrial base of returning entrepreneurs in Dongxiang District, Fuzhou City, Jiangxi Province, more than 4,000 mu of Phyllostachys praecox bamboo shoots have ushered in the harvest period. The villagers are busy collecting, sorting, loading and exporting, and the harvesting period will last until the end of March 2024.

　　At present, in Shaohuomiao Village, Chuanhui District, Zhoukou City, Henan Province, the edible fungi planted in the intelligent cabin are welcoming the harvest season. Due to the computer control of temperature and humidity in the process of edible fungi cultivation and scientific management, the annual income of the two cabins can reach about 100 thousand yuan.

　　In order to ensure the continuous and efficient supply of vegetables in winter, Shenzhou City, Hebei Province set up 20 vegetable technical guidance groups to scientifically guide growers to plant in succession, so that the greenhouse will not be idle in winter and the supply of vegetables will be uninterrupted.

　　Various measures have been taken to prevent cold wave and ensure vegetables to survive the winter smoothly.

　　In view of the recent cold wave weather in many parts of the country, the production and supply of vegetables are facing challenges. All localities actively take scientific measures to do a good job in cold protection and warmth to ensure the smooth wintering of all kinds of vegetables.

　　In Hengyuan Street, Linyi County, Shandong Province, in order to cope with the sharp cooling and strong wind brought by the recent cold wave weather, the local government sent meteorological service information to vegetable farmers in a targeted manner and provided "point-to-point" assistance. According to the growth situation of different vegetables, it provides targeted scientific anti-freezing schemes for vegetable farmers to ensure the smooth listing of vegetables.

　　In the vegetable greenhouse in Maozhuang Town, Taikang County, Henan Province, agricultural technicians are checking the growth of vegetables and urging farmers to do a good job of heat preservation and antifreeze to avoid the sudden drop in temperature from affecting the growth of vegetables.

　　In Huai ‘an District, Huai ‘an City, Jiangsu Province, in order to cope with the coming cold wave, Yao Bingqing, a big planter, is busy covering 31 newly installed facilities in 2023 with two or three films before the rain and snow, and strengthening the cold protection measures through "three films".

　　The seasonal decline in the overall price of vegetables is expected to pick up later.

　　Affected by factors such as area increase and yield increase, the overall price of vegetables has fallen seasonally, and some varieties are significantly lower than the same period in 2022.

　　Haijixing International Agricultural Products Logistics Park, located in Changsha County, Hunan Province, is the largest vegetable hub in Central and South China. Vegetables from more than 20 provinces in China gather here, and more than 10,000 tons of vegetables are sent from here to Guangdong, Guangxi and other provinces and regions every day, ensuring the vegetable supply of residents within 600 kilometers.

　　According to the relevant person in charge of the Ministry of Agriculture and Rural Affairs, recently, the prices of some vegetable varieties have fallen sharply, mainly due to the high price in 2022. In 2023, the planting area increased steadily, the weather in autumn and winter was warmer, the yield level was significantly improved, and the local vegetables were listed on the market, and the staged supply pressure increased. From the later trend, vegetable prices will turn into seasonal upward trend according to the perennial law.

　　Near New Year’s Day and Spring Festival, the holiday effect is gradually emerging, and the demand for vegetable consumption is expected to increase. Because vegetables have increased steadily in the field area, winter storage vegetables such as cabbage and radish have increased in the early stage, the overall supply of vegetables is guaranteed, and it is unlikely that the price of vegetables will rise sharply.
