Comparing "gaoxing" and "kaixin"

Both 高兴 (gāoxìng) and 开心 (kāixīn) can translated to mean "happy." Both can be used in formal and informal settings and are often paired with intensifiers like 很 (hěn), 太 (tài), 非常 (fēicháng). A key difference is 高兴 is both an adjective and a verb (meaning "to be happy"), whereas 开心 is only an adjective. A final difference is 高兴 is used in fixed patterns like when you meet someone for the first to and say “pleased to meet you.”

To say “pleased to meet you” use 高兴

This sentence is not a traditional Chinese saying; it's more of a translation from English (or perhaps other European languages). In this case it's not that 开心 (kāixīn) is necessarily wrong; it's just that there's already a set phrase that everyone knows, using 高兴 (gāoxìng).

  • 认识 你 很 高兴。 Rènshi nǐ hěn gāoxìng.Pleased to meet you.
  • 很 高兴 认识 你。 Hěn gāoxìng rènshi nǐ.Pleased to meet you.

We're using "pleased to meet you" instead of "nice to meet you" because "pleased" is closer to "happy," but you can translate that as "nice" in your head if you like.
