If there is a so-called "Battleship China Changbai", then it can play the following battlefields.

Well, let's assume it exists. If China's navy at that time had quality beyond the world average and excellent commanders, then the battleship Changbai you mentioned could compete with Yamato Hotel (funny).

Daiwa General Manager owns a triple-mounted 94-type 45-caliber 460mm naval gun, as well as various auxiliary guns and air guns, and its firepower is abnormal in battleships. But its observation ability is very backward, and most battleships equipped with radar can hang it outside the maximum range. What? You mean its aerial reconnaissance plane? Come on, what's the use of seven tops? Directly swept down by anti-aircraft guns.

In addition, the officers and men of the Japanese joint fleet on the Yamato have low combat literacy and even no actual combat experience at all, and suffered losses in the US Pacific Fleet (or Chinese Fleet) after the naval battles in Midway Island and Leyte Bay. Off-topic, the air defense capability of this cargo was a big joke before the modification of 1945, and later it was a small joke. That type of empty bomb is the stupidest design I have ever seen, and it is also the main gun launch. A piston plane that can hit hundreds of kilometers per hour at the fastest speed basically depends on the mood of the gods. And this thing is basically a dead end if it leaves the fleet. Destroyers and carrier aircraft have ten thousand ways to detonate it. All right, back to the point. My answer is that the imaginary battleship Changbai you mentioned is enough to defeat the battleship Yamato as long as there is no accident.
