Teacher, I always confuse Past Simple and Present Perfect. When do I say "I lived" vs "I have lived"?

Excellent question, Vannak! The key is **connection to the present**.

• "I lived in Japan for 2 years" (Past Simple) = The action is **100% finished**. You don't live there anymore.
• "I have lived in Japan for 2 years" (Present Perfect) = The action started in the past and is **still continuing right now**. You still live there! ⏳
