Update and renovate gas pipelines and strengthen gas safety inspections.

1. Renovate gas pipelines. Implemented by a professional and qualified construction team, while the gas facilities are being updated and renovated, the installation of gas safety alarm devices is also progressing simultaneously.

2. Strengthen gas safety inspections. During the gas safety inspection, it was found that some gas pipelines were aging and corroded. Some pipelines were installed in unreasonable locations underground or inside walls, making them inconvenient for maintenance. Once a fault occurs, it is difficult to find it.
