No gas. Why?

No breath may be due to the following reasons: 1. Gas pipeline failure: gas pipeline may be blocked, broken and other failures, leading to gas failure. 2. Gas companies stop supplying gas: Gas companies may stop supplying gas for reasons such as maintenance and renovation. 3. Failure to pay the gas fee: If the user fails to pay the gas fee for a long time, the gas company can stop supplying gas. 4. Insufficient natural gas resources: If natural gas resources are insufficient, gas companies may limit supply or stop gas supply. 5. Weather reason: Under extreme weather conditions, such as rainstorm and snowstorm, the gas pipeline may be affected, resulting in the inability to supply gas.
