Have you ever seen a pumpkin as huge as a wheel? A botanical garden in Shanghai's Songjiang District developed 70 to 80 such giant pumpkins, each more than 60 centimeters across and weighing more than 60 kilograms. A single pumpkin costs no less than 1,000 yuan (US$120) and can feed 100 people.  The pumpkin seeds were imported from India.
