Take her a gift, doesn't have to be extravagant.  Wrap it in red (good luck) and present it to them with both hands; culturally it's as if you were giving a part of yourself to them.

Can set yourself apart as a respectful client, and a good reputation will come back in your favor.

Many Asians will take several weeks of vacation around this holiday, so gifting early is fine.  Don't be surprised if they don't know how to respond right away - you'll catch them totally off guard.  But in a good way.
