It is said that buildings should be made according to ground.
Does it mean a building which is made according to soft ground can't be made on hard ground? Or is it only for opposite?
What happens if a building is made according to soft ground on hard ground?

It is said that buildings should be made according to ground. Correct.
Does it mean a building which is made according to soft ground can't be made on hard ground? Or is it only for opposite? Soft ground requires additional and deeper supports.
What happens if a building is made according to soft ground on hard ground? If a building structure is designed for soft ground is erected on hard ground, no problem. If the opposite, it may sink into the soil like the Leaning Tower of Pisa or blow over in a strong wind.
So buildings should be made accordingly when it is on soft ground. It doesn't matter when it is on hard ground?
In any case, buildings must be anchored against wind force and uplift. Otherwise, no. Hard ground provides no advantages. Soft ground makes a building subject to sinking under its own weight, being blown over or lifted up by wind.
I am talking for earthquake.
Designing for an earth quake is not the same as the other two. Buildings designed that way provide for a degree of lateral movement for the entire structure and the frame itself should be more flexible. But if you are designing for high wind, earthquake and soft ground, better to design low-rise or single storey.
Buidlings should be made according to ground for earthquake. What I ask is, is it only matters for soft ground.
I live in an earthquake country.
I figured you were Turkish or Italian. Soft ground is the most problematic although ling pilings can mitigate that. I am sorry for your country's loss.
If a building is designed for soft ground and built on hard ground, it may not necessarily be a problem. However, if the foundation and structural design of the building were not appropriately adapted for the harder ground, it could lead to structural issues, such as uneven settling or cracking.
The same would apply if a building designed for hard ground were built on soft ground, as the foundation and structural design may not be able to withstand the soil's softness and instability.
I asked for earthquake, by the way
An earthquake is an earthquake. Shallow foundations such as spread footings are not suitable in areas with high seismic activity, whether the ground is hard or soft. You'd want a deep pile foundation, but the type of pile depends on soil type.
So, a building can be designed for soft ground on hard ground? It doesn't matter for hard ground?
It begins to lift up and then fly away
