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.
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.
