Nanmenwai Street is the earliest existing street in my city, the most abundant historical and cultural relics. Whether it is Tang Song or Ming and Qing Dynasties, Nanmenwai Street has been a collection of shops and shops, and is an important economic center in Yangzhou. Today's South Gate Street, the bustling no longer, but the houses on both sides are still the style of the Ming and Qing Dynasties. The mottled blue bricks and tiles silently tell the vicissitudes of history.
