Explanation of "晚上好 (Wǎn shang hǎo)" in Chinese:

"晚上好" is a polite evening greeting, equivalent to "Good evening" in English. Here’s the breakdown:

晚上 (Wǎn shang)

Refers to the "evening," typically spanning **from sunset to late night** (e.g., 6:00 PM to bedtime) in Chinese daily usage. It follows "下午好 (xià wǔ hǎo, good afternoon)" and is distinct from "深夜 (shēn yè, late night)."

好 (Hǎo)

Literally "good," used to wish someone a pleasant evening.

Tone and usage:

Formal-friendly and suitable for both casual and professional contexts. It’s commonly used to greet family, friends, or colleagues at dinner time, social events, or in workplace interactions during evening hours. The phrase is more formal than "你好 (nǐ hǎo, hello)" but less formal than "晚安 (wǎn ān, good night)" (which implies bedtime).

Example:

At a dinner party: 晚上好，欢迎来参加聚会！ ("Good evening, welcome to the party!")
