Is it a joke to cross the river by feeling the stones?

This is no joke. We should have a historical perspective. We can't just look at one aspect because of extremely one-sided economic reasons. In the international environment at that time, the Soviet model was unreliable and the American model was not so good. Therefore, there is no lesson on how to lead a poor China to prosperity. All policies can only cross the river by feeling the stones. This was by no means a joke at that time, and it should not be a joke now.

It's about Chairman Mao.
