统一
tǒngyī · HSK 4
unify
🤝 统 = govern/unite + 一 = one; literally 'govern as one'
统 means to govern or bring under one command; 一 is the number one. Together they mean to merge separate parts into a single whole — to unify or integrate.
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.'
