Why is the animal world not filmed by China people themselves?

Only BBC and National Geographic can produce high-level animal documentaries. This thing needs a very high level of outdoor photography, and it costs a lot. The BBC filmed a blue whale, which has been tracking and shooting at sea for three years. Without true love for nature, without adventure and challenge, it is impossible. Even domestic TV dramas are shot to pieces, let alone this field. When can you make a film of this level of Hollywood's top blockbusters? Think again.
