Mohammad Harouni is a young tour leader who lives in Bandar Kong in southern Iran and shows tourists the old leng-building workshop and other sights of the area. Bandar Kong leng-building is 1,200 years old and was registered in the UNESCO Intangible Cultural Heritage List in 2011 under the name of Iran, but now, due to technological advances and heavy construction costs, this industry has declined and is being forgotten.
