Most of the time spent is preparing and harvesting. In between you watch things grow and maintain. When nothing is growing...at least, my in-laws in China...drink, gamble (mahjong, card games) and hang out with other villagers.

They all pooled their money together for some heavy machinery too...so even that has cut down a lot of time spent on prep & harvesting.

You could get jobs in the city when there's no farming to do, too. But you'd need a place to stay that doesn't eat up your wages. It's easy to do if you have family in the city already and just crash in their living room.

Another question to ask is what do you do when you're near retirement and too old to work? Well, you live with your kids and they take care of you with their income and chores. It's not like now where you're sent off to a nursing home and retirees need to be able to afford that.
