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.
Kolkata Business Pulse
- Culture Intellectual and heritage-focused. Business often involves longer discussions and consensus.
- Lunch Break 1:30 PM - 2:30 PM.
- Pro Tip Best reached between 11:30 AM and 4:00 PM. Avoid the 1:30 PM - 2:30 PM lunch window. Business culture is intellectual and values detailed discussion; avoid overly aggressive "hard-sell" tactics. Note that the city slows down significantly during major festivals like Durga Puja.
