peak

In Chinese, the word '高峰' (peak) is used mainly to refer to the highest point or maximum of something. It could be used to describe a mountain's highest point or the highest or max point in a statistic. Like in English, '高峰' can be used literally and figuratively, e.g., '工作的高峰' means 'peak of work', symbolizing the most intense or busiest period.
