When was lettuce introduced to China? Is lettuce a genetically modified vegetable?

Lettuce is native to the Mediterranean coast of Europe and domesticated from wild varieties. The ancient Greeks and Romans ate it first.

Lettuce has been introduced into China for a long time, and the exact date cannot be verified. It has been introduced to China for at least 600 years.

However, the official kiln in Shishan Town, Nanhai has a history of 1 100 years, which originated in the late Tang Dynasty, Five Dynasties and Ten Kingdoms. South Hanwang was named after setting up a pottery kiln in the official kiln. There are many unique folk cultures, the most prominent of which is the official kiln lettuce meeting, which lasted nearly 600 years.

Lettuce is not genetically modified, and there was no such technology at that time.
