The first day I would build
Give the city one clear route before adding extras.
- Start with Taierzhuang Ancient City and Grand Canal while energy is high.
- Use Taierzhuang War Memorial as the natural reset instead of crossing town too early.
the easier plan is Taierzhuang Ancient City first, canal and memorial nearby, Weishan Lake separately. 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 Xuecheng just because it looked close on a map.
