高低

• Pinyin: gāo dī
• Hanzi breakdown: 高 (tall, high); 低 = 亻 + 氐 (low, downward — person bending low)

Meaning

Height difference; high and low; relative level or position. Also used idiomatically to mean a sense of propriety or awareness of social hierarchy.

Used literally to describe physical elevation differences, and metaphorically for social hierarchy, skill levels, or comparative outcomes. The phrase 不知高低 means failing to recognise one's social standing or lacking tact. Common in both formal and colloquial contexts.

Examples

1. 山峦起伏，高低错落，在晨曦的映照下呈现出一幅令人心旷神怡的壮美画卷。 The mountains rose and fell in uneven layers, and in the morning light they formed a magnificent scene that felt wonderfully refreshing.
2. 这两位棋手棋力相当，难分高低，比赛持续了整整四个小时才决出胜负。 These two chess players were evenly matched, and it was hard to tell who was stronger; the match lasted a full four hours before a winner was decided.
3. 他在领导面前说话不知高低，屡次冒犯，终于引起了上司的强烈不满。 He had no sense of propriety when speaking in front of the leadership and repeatedly crossed the line, which finally provoked his boss’s strong displeasure.
