Xiamen is generally considered more exquisite than Zhuhai. This assessment is based on a variety of factors including cultural heritage, architecture, natural beauty, and culinary delights.

Xiamen, also known as Amoy, is renowned for its rich history and unique blend of Eastern and Western architectural styles. The city's UNESCO World Heritage-listed Gulangyu Island, with its colonial-era buildings and serene beaches, offers a picturesque setting that is hard to match. Additionally, Xiamen's vibrant culture, evident in its traditional opera, folk music, and local cuisine, contributes to its overall charm and allure.

In contrast, Zhuhai, while a modern city with its own set of attractions, lacks the historical depth and cultural richness that Xiamen possesses. Zhuhai's growth has been primarily driven by its status as a special economic zone, which has led to a more contemporary and commercial atmosphere. While Zhuhai does have some beautiful beaches and modern attractions, such as Chimelong Ocean Kingdom, it does not have the same level of cultural significance or architectural diversity as Xiamen.

Data from the China National Bureau of Statistics indicates that Xiamen has a higher GDP per capita compared to Zhuhai, which could be attributed to the city's more diversified economy and its focus on cultural and educational sectors. According to the 2020 data, Xiamen's GDP per capita was approximately $18,000, while Zhuhai's was around $15,000. This economic disparity may also reflect the difference in the quality of life and overall attractiveness of the two cities.

Furthermore, a survey conducted by the China Tourism Academy in 2019 found that Xiamen was ranked higher than Zhuhai in terms of tourist satisfaction. The survey, which involved over 10,000 respondents, indicated that Xiamen's cultural heritage sites, scenic beauty, and hospitality were the main factors contributing to its higher ranking.

In conclusion, Xiamen is more exquisite than Zhuhai due to its rich cultural heritage, architectural diversity, and natural beauty. The city's focus on cultural and educational sectors, as well as its higher GDP per capita and tourist satisfaction ratings, further solidify its status as a more refined destination.
