Bao is cooking soup with winter bamboo shoots.

老包正用冬笋制作一道家常笋汤。

The winter bamboo shoot is seasonal and hard to preserve.

冬笋时令性极强又难以保存。

But Bao has instead used Suichang winter bamboo shoot that is 20 times more expensive.

但是老包却使用，价格高出20倍的遂昌冬笋。

The winter bamboo shoot hides in the earth, and is hard to find on the surface.

冬笋藏在土层的下面，从竹林的表面上看什么也没有。
