In the second quarter of 2019，the documentary Breakfast in China and The Planets were exclusively broadcast on Tencent Video. Breakfast in China has been loved by Internet users because of its shortness，lightness and vitality. The Planets adds plot factors into the universe，and builds a popular context for the story of the universe. These two works show the layout and achievements of Tencent Video in the documentary field，from which we can also see the development direction of Tencent Video documentary. Breakfast in China represents that Tencent Video has participated in and gradually laid out the self-made content of documentary and joint production. The Planets is the fruit of the continuous cooperation between Tencent Video and the international head documentary production company. From the purchase of copyright to the self-made content，Tencent Video documentary has taken a solid step. The category of food and natural science are the two that Tencent Video is good at，and have shown advantages，but in terms of form，these two categories have changed a lot compared with three years ago. Tencent Video’s thoughts on the category，form and industry of documentary are all permeated in these changes. In the future，Tencent Video will still give consideration to self-made and copyright purchase，but the category opening，form innovation and industry promotion of documentary will also become a crucial part.
