Hello Rowling,Nanchang has a monsoon-influenced humid subtropical climate with four distinct seasons. When staying in Nanchang, you’d better try the Nanfeng honey tangerines, which are noted as the "king of tangerines", and Site liquor and Lidu writing brushes, showing strong local characteristics.
But please note that pickpockets are everywhere, especially near Zhongshan Road area. They can steal things even from your shirt pocket! Never leave your belongings unattended in restaurants or shops, even if it is a upper-class one. Apart from that, the city is quite safe.
