Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
Shenzhen Business Pulse
- Culture Hardware capital of the world. "Shenzhen speed" means ultra-fast prototyping and decision making.
- Lunch Break 12:00 PM - 1:30 PM.
- Pro Tip Call between 9:30 AM and 11:30 AM for the quickest decisions. This is the fastest-paced city in China; expect your contacts to value speed and efficiency above all else. Avoid the 12-1:30 PM lunch/nap window. Respond to follow-ups immediately to maintain momentum.
