The US has painfully acquired the expertise and skills over half century. Thousands of aviators and sailors have died over decades until the current level of expertise has been reached.

Chinese have studied and copied everything. They translated USN carrier vessel flight deck manuals into Chinese and adopted it almost verbatim. Even the colors are the same. That's really smart thing to do. Trying to innovate and do your own thing starting from scratch because you have the false sense of pride and need be different would be stupid.
