You might remember the meaning of the character 拼 with this easy mnemonic:
I'm trying to piece together an umbrella (扌) from scratch but I keep getting glue stuck in my eyebrows (丷). One (一) umbrella is too much for me to handle with my two hands (廾). I guess I'll have to give up on staying dry (干).
Using mnemonics to remember the meaning of Chinese characters like has a huge impact on how long to learn Mandarin it takes.
