The basic situation of food in our country is self-sufficiency, a certain amount of imports and reserves. The output of grain in our country has increased annually, however, as a result of policy adjustments and other factors like environmental pollution, together with a large population base and the trend of excessively popu- lous growth, the growth of grain output is relatively slow, which will be harmful for our grain security as well as the healthy development of the na- tional economy. In this case, several solutions could be tried, such as improving the level of science and technology, adjusting industrial policies and controlling environmental pollution. Besides, we ought to strongly advocate thrifty behavior to increase income and reduce expenditure.展开更多

China has unveiled guidelines on improving China’s strength in transportation. By 2035, an accessible travel service system should basically be built, according to the guidelines jointly released by the Communist Party of China Central Committee and the State Council. It is of great practical significance to accelerate the construction of an accessible transportation environment in the new era, which can improve the equalization of public services and promote the safe, convenient, and comfortable travel of the disabled and the elderly. In line with the development status of transportation in China, and through an analysis on the requirements for building a country with a strong transportation network, this paper proposes the framework and content for the establishment of an accessible transportation system in China.展开更多
