1. Rebuild the house: If conditions permit, you can consider rebuilding the house, and choose a place with lower terrain than the yards on both sides, which can reduce the sense of oppression and increase safety.
2. Improve the drainage system: If the house has been built, the drainage system can be improved to prevent the yard and the house from being flooded, thus reducing the height difference between the yard and the house.
3. Planting plants: Planting some plants around houses and yards, such as trees and flowers, can beautify the environment and cover the part higher than the yard, thus reducing the height difference.
4. Build a fence: You can build a fence to separate your yard from the parts higher than the yard on both sides to increase the safety of your yard.
5. Reorganize the land: If conditions permit, you can rearrange your yard to make it lower than the yards on both sides, thus reducing the height difference.
In a word, rebuilding the house is the best way to solve this problem. If conditions do not permit, other methods can be considered to improve.
