Located in California, San Francisco is a port city and an internationally renowned tourist destination. It is also the place where the 2023 APEC Economic Leaders' Meeting is being held. To mark the occasion, CGTN has launched a special program called "Tunes from Two Cities," offering viewers a journey around Shenzhen and San Francisco through music to discover their dynamism and pioneering spirit. Su Meng is a classical guitarist who moved to San Francisco several years ago and is currently a professor at the San Francisco Conservatory of Music. In "Tunes from Two Cities," Su Meng expresses her impressions of San Francisco mellifluously through her rendition of Johann Sebastian Bach's "Courante."
