Because Lin Qiang's oil source is CNOOC, their oil depot is in Jinning, and even PetroChina and Sinopec have warehouses there.

Last time, the newspaper published that their strong forest index was better than two barrels of oil. Unfortunately, there are still not enough exits. Private enterprises should work harder.
