In Hong Kong, most people enjoy delicious foods especially those from Fast Food Store. So, how much do you know about the process of making your favourite one? I am glad to be a gas engineer who works in gas production, networking and utilisation. When I first stepped into this field, I was an engineering graduate trainee, learning from the production of gas and its manufacturing processes, the magnificent transmission network buried underground to every single gas-fired catering equipment. You would wonder how much effort that gas engineer put behind each meal. Come and join us and contributing people a more comfortable life.
