Because I don't live there and rarely go to Shenzhen, I can't use it... It's an older version without the transportation integration feature, and has a balance of 1.1. I can also offer free registration and delivery if you prefer regular mail (which saves on postage).
If you have a QR code address, you can simply leave a message, and I will send it via regular mail. If you don't have a QR code or prefer not to share your address publicly, you can add me on WeChat with the username ChinenInori.
