Defining upper and lower limits

Chinese-grammar-wiki-xia.jpg

To specify "more than" or "less than" a certain amount, or "within" a certain amount, you're going to want to use some of these common words: 以上 (yǐshàng), 以下 (yǐxià), 以内 (yǐnèi), and 以外 (yǐwài). All are "nouns of locality," or 方位词 in Chinese.

以上 and 以下

以上 and 以下 mean "more than"/"above" and "less than"/"below," respectively. Generally they are non-inclusive, meaning that when you say 十岁以下 you mean "less than ten years of age," up to ten, but not including ten years old. In actual usage, however, this fine point may sometimes be fudged a little.

Structure

Amount / Level + 以上 / 以下

Examples

  • 十 岁 以下 的 孩子 不用 买 票 。Shí suì yǐxià de háizi bùyòng mǎi piào.Children under the age of 10 do not need to buy tickets.
  • 我们 需要 有 两 年 以上 工作 经验 的 人 。Wǒmen xūyào yǒu liǎng nián yǐshàng gōngzuò jīngyàn de rén.We need people with two years of working experience or more.

以内 and 以外

Literally, 以内 and 以外 mean "within" and "outside." This spatial meaning can be extended to all kinds of abstracted meanings, as you will see below. Note that 以外 often combines with 除了.
