Guangzhou Business Pulse
- Culture Pragmatic and trade-focused. Known for "Canton Fair" and a deep history in international commerce.
- Lunch Break 12:00 PM - 2:00 PM.
- Pro Tip The 12-2 PM lunch window is very important; avoid calling then. Best times are 10:00 AM - 11:30 AM and 2:30 PM - 4:30 PM. While Cantonese is the local language, Mandarin is the business standard for non-locals. Pragmatism and efficiency are highly valued in this major trade hub.
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.
