China, 2000 years ago: Loyang has risen to become the Capital of the Han Dynasty and one of the four great Capitals of old China.
The economic upturn of the now-flourishing city requires a better supply of basic foodstuffs. These are provided by the local farmers, who plant wheat, pumpkins, turnips, cabbages, beans and leeks in their fields.
After each harvest, the farmers assemble at the gates of Loyang to sell and trade their vegetables. They deliver to their regular customers or lucratively sell their vegetables to passing shoppers. Vegetables can also be traded at Market stalls or used for seed and planted in fields. â€¦
