In response, a team led by Fang Zhiyuan, an academician of the Chinese Academy of Engineering, and Hubei Jinrun Agriculture Development Co Ltd, contributed to the birth of the self-cultivated cabbage seed Sitedan in 2013. Five years later, the locally bred seed stood out, contributing to China's self-dependence on seed growth.

This new seed variety suits the Yangtze River's climate for its resistance to frost and cracking, with a harvesting period that extends into February. These features have earned fame in domestic and foreign markets.
