Creating mnemonics has been so helpful when I have two similar kanji and can’t remember which one is which, but my mind is blanking on this one. I’ve done a quick google but can’t find anyone else struggling with these two kanji, so I would super appreciate any help with creating a way to decipher them.
An example of a mnemonic that worked great for me; 石 vs 右 - The kanji for stone has a flat top like a smooth stone.
For me, 負 is “prison clam will lose”
頁 – is geoduck, which, for a long time, I thought was some geodesical tool, like a theodolite. It even looks a bit like a theodolite. It turned out not to be the case, but by that time I’ve already managed to memorise it.
