Is there a standard for opening the plug for the first time?

After residents use natural gas and gas group to lay pipelines, users need about 3,000 yuan to open an account, including installation of flowmeter, bank account opening, pipeline entry and maintenance. If the previous household has opened an account, the pipeline has been laid in place or the property has been forcibly installed in the gas company once, the occupancy of the household is called unlocking, ranging from tens to hundreds of yuan.
