Should I bring Chinese currency, or can I exchange it when I get to Shanghai? Are credit cards widely accepted?

When traveling to Shanghai, it is recommended that foreigners bring a small amount of RMB to meet initial cash needs, but they can also choose to exchange money after arriving in Shanghai. Foreign currency exchange services are widely available in Shanghai, with facilities distributed at airports, star-rated hotels, bustling business districts, and tourist hubs, covering all 16 administrative districts of the city. The two international airports provide seamless foreign currency exchange services, ensuring that foreign visitors have access to exchange services without any gaps right from their "first stop" upon entry. Additionally, cash ATMs and CRS machines in Shanghai can accept foreign cards for RMB cash withdrawal. Credit cards are widely accepted in Shanghai. Foreign visitors holding overseas bank cards with Unionpay, Visa, Master, or other recognized logos can directly make card payments at merchants displaying the corresponding acceptance logos. The acceptance of foreign cards in Shanghai has basically covered key merchants in various tourism and lifestyle scenarios, including airports, major business districts, three-star and above hotels, 3A and above scenic spots, large commercial complexes, characteristic tourist streets, duty-free tax refund stores, and convention and exhibition centers, with continuous expansion of coverage.
