My mother bought a lottery gold necklace when she traveled to Hong Kong. How can I return it?

Did you return it? You can return it by calling directly. I was fooled by the tour guide in Hong Kong and bought it there. Refund and give them a handling fee, which is the commission that Hong Kong tour guides should have earned. Contact the tour guide in China. When you leave in China, someone will go there to help you return it. You can definitely return it, and I remember that the invoice should say lifetime return.
