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.
Tianjin Business Pulse
- Culture Major port city. Practical, industrial, and trade-oriented.
- Lunch Break 12:00 PM - 1:30 PM.
- Pro Tip Aim for 10:00 AM to 11:30 AM. As a major northern port, business is practical and industrial. Close ties with Beijing mean a similar emphasis on hierarchy and formal protocol. Avoid the 12-1:30 PM lunch break and major public holidays.
