上流

• Pinyin: shàng liú
• Hanzi breakdown: 上 = upper/above; 流 = 氵(water radical) + 㐬 (flowing/phonetic) = to flow/stream — 上流: the upper flow or reaches; upper social stream

Meaning

The upper reaches of a river; also: the upper class or elite social stratum, referring to those with elevated social standing, wealth, and refined tastes.

In the geographical sense, refers to the upstream portion of a river — where water flows faster and is generally less polluted. In social contexts, 上流社会 (upper-class society) refers to the wealthy elite and socially prominent. The social meaning carries a neutral-to-slightly-elevated register in formal use, but can imply exclusivity or elitism in critical contexts.

Examples

1. 长江上流地区水流湍急，峡谷地形复杂，虽然水能资源丰富，但生态保护的压力也迫使相关部门在水电开发与环境保护之间寻求审慎平衡。 In the upper reaches of the Yangtze River, the current is swift and the canyon terrain is complex. Although hydropower resources are abundant, the pressure to protect the ecosystem also forces relevant departments to seek a prudent balance between hydropower development and environmental protection.
2. 这部小说以二十世纪初的上海为背景，细腻描绘了上流社会的奢华生活与其背后隐藏的权力角力、阶层固化以及道德困境。 Set in early-20th-century Shanghai, this novel delicately depicts the luxurious life of the upper class and the hidden power struggles, rigid social stratification, and moral dilemmas behind it.
3. 河流上流地区的水质直接影响中下游居民的饮水安全，因此上游地区的工业排放标准历来是环保部门重点监管的核心议题。 Water quality in a river’s upper reaches directly affects the drinking water safety of residents downstream, so industrial discharge standards upstream have long been a key focus of environmental regulators.
