一味
yīwèi · HSK 7
blindly
一味 = one (一) + flavor (味): stuck on a single taste, so doing it one way blindly
Decomposes as 一 one plus 味 flavor or taste. A person who wants only one flavor refuses every other option, which is the sense of doing something blindly or stubbornly, one fixed way.
一 — single horizontal stroke
一 is one of the simplest pictographs in Chinese, depicting a single horizontal line to represent the number one. It has retained essentially the same form since oracle bone script over 3,000 years ago. By extension it also means 'first,' 'whole,' or 'same.'
