After a full year of work, they came away with nothing — everyone was very disappointed.
Tips
usage
Primarily literal — describes crop failure after drought, flood, or pests. The figurative 'come away with nothing' sense (from a project or investment) is common but secondary.
memory
颗粒 = 'grains' (of rice or wheat), 无收 = 'no harvest'. Picture an empty threshing floor — not a single grain to gather.
