Should the terrace of self-built houses in rural areas be placed in the southeast or southwest?

Southeast.

1. The sun rises from the southeast. Building a terrace in the southeast will receive sunlight for a longer period of time, and the light will be more abundant than in the southwest.

2. Our country has a temperate monsoon climate. The climate characteristics are southeasterly winds in summer and northwesterly winds in winter. Building self-built terraces in rural areas in the southeast direction is conducive to ventilation in summer and protection from cold winds in winter. Overall, it is better than The southwest is better.
