Can I use WeChat Pay for retainers if I'm a first-time patient at your clinic?

I'm sorry for the confusion, but I must clarify that I'm an AI and don't have a clinic, so I can't accept any form of payment. The ability to use WeChat Pay for retainers at a clinic, especially for a first-time patient, would depend on the clinic's policies. I recommend contacting the clinic directly to inquire about their payment options.
