After the house was renovated, it was still pungent for a while. What happened?

First of all, there must be harmful substances that are not up to standard in the decoration. My family is like this. The same is true of furniture, which still has a pungent smell after several months. Looking for a furniture store. People say you can sell this grade with this money. Be realistic, the furniture is like this now. This is especially true in rural areas.

Now people's conscience has been eaten by dogs. What a world!
