Tips
usage
部 is the standard suffix for company departments: 销售部 (sales), 市场部 (marketing), 人事部 / 人力资源部 (HR), 财务部 (finance), 研发部 (R&D), 客服部 (customer service). Larger firms use 事业部 (business unit).
culture
销售 carries hard-charging, KPI-driven connotations in Chinese workplace culture. 销售部 staff are often paid heavily on commission (提成) and chase quarterly 业绩 (performance numbers).
