CCTV documentaries can actually be watched for free on many video websites. For example, Tencent Video has compiled some documentary series and video columns, which is very convenient to search.

But if you want to systematically review all CCTV documentaries (at least in recent years), you can go directly to the CCTV website → CCTV Documentary Channel

Very comprehensive, not just CCTV Documentaries made by myself, as well as imported foreign documentaries, such as the National Geographic series. Although the entire series is not introduced, it is good to be able to watch the Chinese version effortlessly in China. If you are the original fan, go to Baidu Disk and other places to find it. There are a lot of resources.

In addition to the main themes, CCTV’s own documentaries also include categories that explore nature and history and culture. They are actually very interesting to watch. China's documentary shooting technology has been developing over the years, and "A Bite of China" became the loudest hit, making Chinese people gradually more accepting of domestic documentaries. Although it is still far behind the old BBC, National Geographic and the like, think about it. In the past cultural development process, China has never followed a "scientific exploration" type of route. We can also understand why China’s understanding of the subject of documentaries is so lagging behind. It is always developing and will get better and better.
