Comparing "changchang" and "jingchang"

Both 常常 (chángcháng) and 经常 (jīngcháng) express similar concepts, though using them properly requires attention to some small details.

Used as an Adverb

常常 and 经常 both can be used to express frequency, meaning "often," and that the time between each time it happens is very short. In this case, they are interchangeable.

Structure

常常 / 经常 + Verb

Examples

• 我 常常 收到 垃圾 短信 。Wǒ chángcháng shōudào lājī duǎnxìn.I often receive junk messages.
• 你们 经常 加班 吗 ？Nǐmen jīngcháng jiābān ma?Do you often work late?
• 他们 常常 吵架 。Tāmen chángcháng chǎojià.They often fight.
• 他 经常 不 吃 早 饭。Tā jīngcháng bù chī zǎo fàn.He often skips breakfast.

However, 常常 can be shorten for 常 while you can't do this with 经常.

• 你们 会 常 来 看 我 吗 ？Will you often come to visit me?
• 常 联系 ！Let's keep in touch!

Note that 经常 is also a little more formal than 常常 as an adverb when it comes to written language. But it won't make a difference colloquially.

Used as an Adjective

经常 can also be used as an adjective referring to things that happens very frequently, or you can use 经常性 instead. 常常 can't be used this way.

Structure

经常(性) + 的 + Noun

Examples

• 她 忘 带 钥匙 是 经常 的 事情 。Tā wàng dài yàoshi shì jīngcháng de shìqing.Her forgetting to bring a key is a frequent occurrence.
• 对 我们 来 说 ，处理 顾客 的 投诉 是经常性 的 工作。Duì wǒmen lái shuō, chǔlǐ gùkè de tóusù shì jīngchángxìng de gōngzuò. For us, dealing with customers' complaints is a common job.

Negative Form

经常 and 常常 can share the same negative form 不常. For 经常, you can also simply use 不经常 to negate.

Examples

• 我 不 经常 看 电视 。I don't watch television very often.
• 他 不 常 抽烟 。He doesn't smoke very often.
