What is the direction of China's future population policy in order to achieve the sustainable development of population in economy and society?

The core of social sustainable development is the sustainable development of population. At present, the actual fertility rate in China is only 1.4, while the willing fertility rate is only about 1.7, both of which are far less than the reasonable generation replacement rate of 2.3. Facing the dilemma of being poor and old in the future, the direction of future population policy is: planned death+forced birth+introduction of immigrants.
