When someone says "别客气" in Chinese, it's often a polite response after you've been thanked or complimented. In English, there are several ways to convey this sentiment depending on the context and level of formality. Here are some common phrases:

1. "You're welcome."

This is probably the most straightforward translation. It’s simple, polite, and works in both casual and formal settings.

2. "No problem."

A more casual option that implies the task was easy or not a burden at all.

3. "Anytime."

This phrase suggests that you’re always available to help, adding a friendly touch.

4. "Glad to help."

Expressing genuine happiness about being able to assist can make interactions feel warmer.

5. "It was nothing."

Slightly informal, this phrase minimizes the effort involved in helping.

6. "Happy to help."

Another warm response indicating your willingness to lend a hand.

Each of these responses has its own nuance, so choosing the right one depends on who you're speaking with and the specific situation. Practicing these phrases can enhance your conversational skills and leave a positive impression when communicating across cultures!
