What will happen if the hotel is renovated in the near future?

Formaldehyde poisoning. In recent years, there are many new hotels among network celebrities, which are very sought after by tourists. In order to gain an advantage in the fierce market competition of the hotel industry, the storefront was renovated. After renovation, the hotel only started to operate normally after simple ventilation, so if the renovated hotel is close to the renovation year, it will be poisoned by formaldehyde.
