@xia.nan6: Tehran, the capital city of Iran, is the largest city in the country, with a population of over 14 million and an area of approximately 730 square kilometers. As a major metropolis in Western Asia, this ancient city, which dates back over 5,000 years and is home to the Persian civilization, is often referred to as the "Eurasian Land Bridge" and the "Air Corridor between East and West." It is a vibrant city where history and modernity seamlessly blend together! #Iran #Tehran #GlobalTravel
