Learning Chinese can be both a rewarding and challenging journey. One of the many areas that often confuse learners is the subtle differences between words that seem to have similar meanings. A prime example of this is the distinction between 减少 (jiǎnshǎo) and 降低 (jiàngdī).

In this article, we will delve into these differences to help you use these words correctly and naturally in your Chinese conversations.
Understanding 减少 (jiǎnshǎo)
减少 (jiǎnshǎo) is a verb that means “to reduce” or “to lessen.” It is often used when referring to a reduction in quantity or number. Here are some key points to consider when using 减少:

Understanding 降低 (jiàngdī)
降低 (jiàngdī) is also a verb that means “to lower” or “to bring down.” It is often used when referring to a reduction in level, degree, or intensity. Here are some key points to consider when using 降低:
