China's lithography machine has reached the world's advanced level, why do some people say that China's chip industry is still a difficult road ahead?

First of all, China's lithography machine has not reached the world's advanced level, and now China's self-developed lithography function has reached 14nm, while the world's advanced technology has reached 5nm, which is far from it.

Because the leading technology of lithography machine is basically monopolized by foreign countries, the road of chip in China is still very long and very difficult.
