The full name of PetroChina is China Petroleum and Natural Gas Group Co., Ltd., and the listed company is China Petroleum and Natural Gas Co., Ltd., which is the largest ministerial-level organ management unit. Both of them belong to several bureau-level secondary units in various regions of the world.

Let me answer your question first. It's the same.

Then I'll mention the secondary sector, which is divided by function, not by product, such as exploration, drilling, transportation, pipeline, equipment, sales, engineering, international, scientific research and so on. If we want to divide the board by product, it is that the society is talking about stock trading and futures, hehe, there is no control rationality. Just like one supermarket specializes in drinks and another supermarket specializes in instant noodles, it is unrealistic.
