Eliminating the marginalization of underdeveloped countries and regions is an urgent task in today's world. This requires the joint efforts of all countries in the world. The global train has started, leading more than 200 countries and regions around the world to the knowledge-based economy society. Train-driven carriages are pulled by connectors. "Connectors" are like two hands, which need to be clenched to transmit traction.
As far as developed countries are concerned, due to the restriction of social mechanism, it is impossible to give huge amounts of money to developing countries and regions for free. However, knowledge products can be enjoyed and can be of great help in technology transfer, education, management and other knowledge and information. In the WTO, some preferential policies have been given to developing countries, but in order to speed up the pace of eliminating the gap between North and South, the existing preferential policies seem to be far from enough.
From the perspective of developing countries and regions, we should have national spirit and ambition to catch up. According to China's experience in poverty alleviation, it is "to help the poor first, and to help the wise first". That is, we must first have the ambition to get rid of poverty and become rich, and to establish ambition and explore ways for countries and regions to get rid of poverty and become rich depends on knowledge, wisdom, science and culture. Therefore, vigorously developing education according to local conditions is the first choice for backward areas to prevent marginalization.
