Rio de Janeiro Business Pulse
- Culture Relaxed but hardworking. Creative and media industries are prominent.
- Lunch Break 12:30 PM - 2:00 PM.
- Pro Tip Best call times are 10:30 AM to 12:00 PM and 2:30 PM to 4:30 PM. "Cariocas" (Rio locals) value an informal and friendly start to meetings. Always spend a few minutes on social pleasantries. Avoid scheduling anything for Friday afternoon as the city begins its weekend transition early.
Shanghai Business Pulse
- Culture Highly competitive and fast-paced. Business is often conducted with a mix of modern efficiency and traditional "Guanxi" (relationships).
- Lunch Break 12:00 PM - 1:00 PM (Nap time is common).
- Pro Tip Respect the 12-1 PM lunch and rest window; lights are often dimmed in offices for naps. The best time to call is between 2:00 PM and 4:30 PM. Avoid calling during major public holidays like Golden Week or Lunar New Year, as business comes to a complete halt.
