处里

处 (chù) is an organizational unit — in Chinese government and large enterprises, the hierarchy often runs 部 (bù, ministry) → 司 (sī, bureau) → 处 (chù, division) → 科 (kē, section). 处里 = 'inside the chù' (the location-marker 里 makes a place noun out of any unit). Distinguish from 处理 (chǔlǐ, to handle/process), which has different tones.

mistakes

Don't confuse 处里 (chùlǐ, 'in the division') with 处理 (chǔlǐ, 'to deal with'): different tone on 处, different second character, different meaning.
