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.
San Francisco Business Pulse
- Culture Innovation-focused and casual. Values disruption, speed, and technical excellence.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Expect a casual, tech-first vibe—informal language and dress are the norm. However, technical competence and speed are non-negotiable. Many in the Bay Area work non-traditional hours, but standard business times remain the safest bet.
