What should I do if I change the floor heating and don't refund the decoration deposit?

Wen's solution is to talk to the main leaders about "meaning" and give some blood to refund the money. Wu's solution is, without saying anything, to follow the responsible leader to work every day and give it to you within half a month. 1. If the whole community is not allowed to install floor heating, I suggest you use "Wen". 2. Excluding the first statement, then you have the right to decorate the house (excluding the damage of the main body and load-bearing structure). Even if the downstairs is flooded, you are responsible for solving it yourself (he won't compensate you for the deposit). It's none of his business to suggest solving it by force.
