Torreya grandis is a special product of Zhuji, Zhejiang Province. It is a kind of nut that is not particularly extensive. Its nutritional composition should be similar to that of ordinary walnuts, but it is rare and tastes good. Generally speaking, a catty is about 100 yuan. Torreya grandis doesn't bear fruit every year like walnuts, but once every three years, so the yield is naturally much less.
