There is no Trademark Office in Chongqing, only Beijing has one, and its address is No. 1 Chama South Street, Xicheng District, Beijing.

If you need to register a trademark, you can choose an agency or apply online yourself. One costs money and the other takes time.

If you want to quickly own a trademark and use the popularity of others to make your own products, you still have to rely on trademark franchise (Chongqing Lu Laosha)
