I saw a boat from Tongguan to Yongji on the Internet, but I didn't see any bookings or comments. Is the project yellow?

I don't know, probably not anymore.

Now the waters in the Tongguan section of the Yellow River are not navigable, some are just recreational speedboats, which usually take about 8 to 10 people, and there are two slightly larger antique cruise ships, which are used for sightseeing. Welcome to Tongguan for tourism.
