In Pudong, hailed as a bastion for intellectual property protection (IPR), even a small peach is under legal protection.

Pudong's suburbs are known for growing succulent Nanhui peaches, sweet Sanlin melons and other agricultural products with a geographical indication (GI), a sign used on products with a specific geographical origin and a reputation due to that origin.

The World Intellectual Property Rights Organization states that there should be a clear link between the product and its original place of origin. Specifically speaking, not all peaches growing in Nanhui are eligible to be tagged with the GI label.
