How big is the biggest gourd in China?

Japan cultivated the world's largest gourd in 2006, which can grow to more than 3 meters long.

There is no such thing in China, but there are dozens of varieties of gourds in China's large-scale gourd planting base: big-waist gourds, middle-waist gourds, small-waist gourds, mini-waist gourds (twisting hands), treasure gourds, large-scale single-bellied gourds, medium-sized single-bellied gourds, long-handled hammer-shaped gourds (kicking legs) and small-sized gourds.
