The first day I would build
Give the city one clear route before adding extras.
- Start with OCT Loft and Dafen Oil Painting Village while energy is high.
- Use Huaqiangbei as the natural reset instead of crossing town too early.
the easier plan is one district cluster by day, waterfront or mall reset later. 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 Shenzhen Bay just because it looked close on a map.
