Is there gas in the south of Huoying Hualong Garden in Huilongguan, Beijing?

The house in Huo Ying Hualong Garden is not a commercial house, but a farm in the northern suburbs sold the house in the name of building a staff dormitory, and bought more houses in the name of the unit. Therefore, many households do not have real estate licenses. 1998, they installed a gas pipeline, but after collecting the money, there was no ventilation. It is not clear whether this is a scam. It's a private package anyway, but it's not for work. If it is true, there are great hidden dangers. If you want to buy a house, you must have a good eye. Don't be cheated. The property here is even more difficult to mention.
