Today i’m going to teach you 4 ways to say
“You are welcome” in Italian.
今天我要教大家说“不客气”的4种不同方式。
1. Prego
Prego is basic and most used way to say
“you are welcome” in Italian. And this
should be like your first choice.
Prego是最基本也是最常用的表达方式。
当你想回答“谢谢”时，这可以是你首选。
2. Nessun problema/Non c’è problema
The second is as you say “No problem” in English.
This is the typical expression that is adapted to
various situations. And if someone tells you thank
you, you can answer “Nessun problema”. It actually
means “Prego”.
这相当于英语中的No problem，适用于各种不同的情形。
和prego意思一样，可以自由选择说哪个。
