This is what modern long distance transmission looks like.[1] This is a 12 gigawatt line running at 1.2 million volts.

China does a lot of this, because the good power sources are in northwest China, and the big loads are in the Southeast.

Did they ever get their ultra high voltage grid going? Last I checked, it was still in the planning stages, and they were still running coal in the east because they couldn’t tap renewable power from the west. Looks like they are still building:

So one link at least according to your video, I would be curious about actual numbers about how much they can move already.

As of 2020 there was about 400 GW of installed UHV transmission in China now.

For comparison, Hoover Dam is about 2 GW.

According to https://rethinkresearch.biz/articles/chinas-uhv-transmission..., they will be at 105 GW by 2025 (the article is dated 2022). 50% of the power on these lines will be from renewables by 2025 (right now at 43%).

I can't find any .cn estimates of UHV capacity.
