The first day I would build
Give the city one clear route before adding extras.
- Start with Yinxu and Chinese Writing Museum while energy is high.
- Use Red Flag Canal as the natural reset instead of crossing town too early.
the easier plan is Yinxu and the writing museum first, Red Flag Canal as a separate Linzhou day. That keeps the day readable instead of turning every good name into a separate detour.
I would rather leave one place for tomorrow than drag a tired route through Linzhou Taihang route just because it looked close on a map.
