谁知盘中餐，粒粒皆辛苦。

Who knows the dishes food, each grain is hard.

三天的学农生活，让我理解了“谁知盘中餐，粒粒皆辛苦”的道理。

The three-day life on the farm work training site helped me understand the Chinese saying "Every grain comes from hard working".

这部令人动容的纪录片使人们想起了妈妈的味道，也使一些人意识到“谁知盘中餐，粒粒皆辛苦”的道理。

The touching documentary reminds some people of their mother, and makes some realize that every grain comes from hard and laborious toil.
