What is the strategic significance of medium and large conventional take-off aircraft carriers and Liaoning ships?

Liaoning ship is the first aircraft carrier of our navy, which is of great significance. Liaoning ship is a large aircraft carrier with a displacement of up to 60,000 tons. Of course, in the 1980s, the 60,000-ton class was already very large, and the American Navy Kitty Hawk class was also 80,000 tons. However, times have changed, and the displacement of large American aircraft carriers has reached 6,543,800 tons. Therefore, some people pointed out that the Liaoning ship was afraid of being downgraded to a medium-sized aircraft carrier, but the author believes that since the Liaoning ship was designed with a large aircraft carrier, it should still be classified as a large one.
