What are the differences between the background of coal-to-gas conversion and gas-to-rural distribution?

The scope of gas supply to the countryside is wider. According to an inquiry on Toutiao today, we learned that the background of coal-to-gas replacement and gas-to-rural areas is that gas-to-rural areas have a wider scope. Coal-to-gas conversion means switching from coal to natural gas, which can reduce coal consumption, reduce sulfur dioxide and smoke dust emissions, and play a positive role in improving regional air quality.
