The first day I would build
Give the city one clear route before adding extras.
- Start with Zhalong Nature Reserve and red-crowned cranes while energy is high.
- Use Longsha Park as the natural reset instead of crossing town too early.
the easier plan is Zhalong Nature Reserve first, Longsha Park or a central meal afterward. 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 Qiqihar Museum just because it looked close on a map.
