You might remember the meaning of the character 程 with this easy mnemonic:
The king (王) is embarking on a long journey, but he's only bringing grains (禾) as food. I guess he won't be stuffing his mouth (口) with luxurious meat and seafood when he's visiting the locals.
Using mnemonics to remember the meaning of Chinese characters like has a huge impact on how long to learn Mandarin it takes.
