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.
Hanoi Business Pulse
- Culture Formal, hierarchical, and relationship-driven. Government presence is strong.
- Lunch Break 12:00 PM - 1:30 PM.
- Pro Tip Best reached between 9:00 AM and 11:30 AM. Business in the capital is more formal and hierarchical than in the south. Relationships with authority and government are often important. Trust must be built through multiple polite interactions and formal introductions.
