The first day I would build
Give the city one clear route before adding extras.
- Start with Congtai Park and Guangfu Ancient City while energy is high.
- Use Wahuang Palace as the natural reset instead of crossing town too early.
the easier plan is Congtai Park and city center first, Guangfu Ancient City or Wahuang Palace 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 city center just because it looked close on a map.
