Which is better, plain or mountain?

Just be simple.

1, the plain is flat, which is convenient for planting and harvesting, and the mountainous terrain is rugged, which is not conducive to crop planting and harvesting.

2. The urban construction area in the plain area is large and the transportation is convenient, which is conducive to the development of the city. The mountainous terrain is not conducive to urban planning and construction, and the development will be relatively backward.
