Hong Kong boss electrical appliances closed down. Can the gas stove I bought before still work?

The boss's electrical appliance in Hong Kong closed down, and the gas stove I bought before can still be used. The service life of gas stoves is eight years. If you haven't used it, you've never used it. You can definitely use it. However, gas stoves are divided into gas, some use gas, and some use natural gas. It is necessary to distinguish clearly before use.
