Ripe goji berries are oblong, plump and delicate. All harvesting is performed by hand, and must be accomplished with care, to avoid bursting the berries. Pickers pull the berries from the bushes on which they grow, and place them in baskets. Once a basket is filled, it is weighed and then the process starts all over again. As with many crops, people who harvest goji berries are paid by the amount they pick in a day. A good harvester can pick as much as 40 kilos of goji berries in a single day.
