能留个联系方式吗？

You use this when you meet someone you like. Or when you need to follow up on business. Just drop it at the end of a conversation. It is a versatile tool for your social kit. You can say it with a smile and a slight nod. Most people will immediately pull out their phone to show you a QR code.

Use it at a networking event after a good chat. Use it at a party when you meet a potential friend. It is perfect for that moment before you say goodbye. If you are at a coffee shop and have a great talk, this is your move. It works for both professional and social settings. It is the 'green light' for future communication.

Do not use it if you have just met and haven't spoken yet. That can feel a bit aggressive or 'creepy.' Avoid using it in high-pressure situations like a funeral or a serious argument. If someone is clearly in a rush, maybe skip it. Also, do not use it if you already have their business card. That just looks like you weren't paying attention!

In modern China, 'contact method' almost always means WeChat. Business cards are still around, but the QR code is king. Asking for a 'contact method' is less invasive than asking for a private phone number. It gives the other person the choice of what to share. It reflects the Chinese value of 'mianzi' or face. It is a polite request, not a demand.

You can make it shorter by saying 加个微信吗？ (Can we add WeChat?). If you want to be extra polite, add 方便 (convenient). For example: 方便留个联系方式吗？ (Is it convenient to leave a contact?). If you are feeling casual, just say 留个号吧 (Leave a number). These variations help you match the vibe of the room.
