Incidentally, rice terraces are the best & most efficient way to cultivate the land since it allows rain water to move down the easily thereby allowing all the terraces to get watered. And ultimately, terraced rice field are a testament to a people's ingenuity!

*Indeed it's big-time ingenuity especially in mountainous areas where the landscape is not as easily arable like that of a flatland where most rice fields are found.

It's like: if you can turn a mountain into a more productive rice field via painstakingly carving it, then you're one ingenious & industrious person!
