1. Find the source of rotten wood: First of all, you need to find the source of the smelly wood. If you find rotten wood, you can take it out and replace it with new wood.

2. Clean the wood surface: If you can't find rotten wood, you can try to clean the existing wood surface. Cleaning agents, such as soapy water or white vinegar water, can be used to clean wood surfaces.

3. Deodorization with activated carbon: Activated carbon is an effective deodorant. You can put some activated carbon in the room to absorb the odor.

4. Increase indoor ventilation: Poor indoor ventilation may lead to odor accumulation. You can open a window or use an air purifier to increase indoor ventilation.

5. Deodorize with fragrance: you can use fragrance to cover up the odor in the room. You can choose your favorite aroma, such as floral or woody.

If the odor problem still exists after trying the above methods, it is recommended to consult a professional deodorant or indoor air quality expert for more professional advice.
