Naturally, the assembly language assembler exceeds the execution efficiency of the C language assembler. Not just in lines of code processed/second, but also in size of code generation. It is kind of apples and oranges comparison though, as they have different goals, imho.

I'm also curious how people remember the assembly instructions and how to use them. Can you teach me?

Is that why fasm was chosen as the compiler for menuetos instead of nasm or yasm?

There is no secret - it's like anything else - practice. Start from the beginning - the 8086 instructions. They work the same on modern processors. Programs are something like 60% move instructions - it's the details that matter. The community teaches - it is enough to join the process.

There's another fasm feature that outshines all the competition. Fasm has the best and most sophisticated macro language in the world (if you only consider "normal" assemblers, because it's rewrite, fasmg really pushed macros to the extreme, for example you can alter the target instruction set with macros in fasmg which is far beyond what "normal" assemblers can do.)

Fasm has an exceptionally good documentation, start there. It explains the instructions in great detail and gives lots of examples on how to use them.

Another good source is Intel Software Developer Manual Volume 2. It is a bit too technical, but explains where the mnemonic abbreviations came from, which makes it easier to remember the mnemonics. For example: "ADC—Add With Carry", "BSF—Bit Scan Forward", "LEA—Load Effective Address", etc. This would make no sense if you use a software to translate this into Chinese, at least basic English understanding is required because mnemonics are English abbreviations.

The best way to learn Assembler is to code something simple at first.
Then more and more complicated.

Ok, thank you for your answer.

When learning the register, it is too difficult to move the data to the register and then want to see the data in the register but do not know how to show it.

Use a debugger like x64dbg, then as your step over each line of code, you can observe the value in registers and flags like screenshot attached below:

...and I thought you could print out the contents of the register just like in C using a command like printf().

Yes, you can do that as well.

Sorry, I'm using a translation software that somehow likes to add the English word "you". I think it's easy to misunderstand.

Chinese does not say "you", why the translation software will add "your", very strange.

Indeed, after translating into Chinese, it becomes difficult to read Chinese, because it is impossible to imagine the scene expressed by the text, and it is impossible to imagine the running track and state of the code.

No worries, it is common to refer to "you" in English. Same like you, at first, I thought it is impolite to emphasize "you" in English, while in Chinese it is not being emphasized.
