["Dashishan's economic backwardness and lack of culture are in stark contrast to the colorful world outside.", 'Instead of waiting for national policy assistance, the local government should adapt to local conditions and develop regional characteristics to escape poverty.', 'Solving the problem of subsistence and clothing in the poor people in some southwestern areas is a priority for coordinated development.', 'A major obstacle to the prosperity of local people is the harsh natural environment.']
