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.
Tehran Business Pulse
- Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
- Lunch Break 1:00 PM - 2:00 PM.
- Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.
