culture coupled with an extravagant Mestizo de Sangley lifestyle, intermarrying either with native Filipinos or with Spanish mestizos. The largest group of Chinese in the Philippines are the "Second Chinese," who are descendants of migrants in the first half of the 20th century, between the anti-Qing 1911 Revolution in China and the Chinese Civil War. This group accounts for most of the "full-blooded" Chinese. They are almost entirely from Fujian Province. The "Third Chinese" are the second largest group of Chinese, the recent immigrants from Mainland China, after the Chinese economic reform of the 1980s. Generally, the "Third Chinese" are the most entrepreneurial and have not totally lost their Chinese identity in its purest form and seen by some "Second Chinese" as a business threat.

Beyond the traditional family and clan associations, Chinese Filipinos tend to be active members of numerous alumni associations holding annual reunions for the benefit of their Chinese-Filipino secondary schools. Outside of secondary schools catering to Chinese Filipinos, some Chinese Filipinos businessmen have established charitable foundations that aim to help others and at the same time minimize tax liabilities.
