A green onion that stands 2.53 meters high was recognized by Guinness World Records as the world's tallest on Sunday during the 2020 China Zhangqiu Green Onion Cultural and Tourism Festival in the Zhangqiu district of Jinan, Shandong province.

Zhangqiu boasts a long history of growing green onions, and was honored as the "home of green onions" by the Ministry of Agriculture in 1996.

The district currently grows 600 million kilograms of green onions on 8,004 hectares, generating more than 700 million yuan ($106.3 million) annually.
