there seems to be nothing interesting in Mingfa Commercial Plaza, just a Ferris wheel and a pirate ship, which is not as interesting as the Bay Park.
You can take bus No.27 and No.1 across the street to get off the terminal ferry and take a boat trip to Gulangyu,
Or take bus No.18 to Xiamen University, take a walk to the beach on Hulishan, ride a tandem bike or take the
BRT.
If you want to eat, you'd better go to Zhongshan Road. Some Xiamen snacks in the small streets there are still very authentic and the prices are not expensive.
Like "Wu Zaitian's" roasted meat dumplings, and "Huang Zehe's" peanut soup are old Chinese brands.
