The Spanish authorities started restricting the activities of the Chinese immigrants and confined them to the Parían near Intramuros. With low chances of employment and prohibited from owning land, most of them engaged in small businesses or acted as skilled artisans to the Spanish colonial authorities. The Spanish authorities differentiated the Chinese immigrants into two groups: Parían (unconverted) and Binondo (converted). Many immigrants converted to Catholicism and due to the lack of Chinese women, intermarried with indigenous women and adopted Hispanized names and customs. The children of unions between indigenous Filipinos and Chinese were called Mestizos de Sangley or Chinese mestizos, while those between Spaniards and Chinese were called Tornatrás. The Chinese population originally occupied the Binondo area although eventually they spread all over the islands, and became traders, moneylenders and landowners. Chinese mestizos as Filipinos During the Philippine Revolution of 1898, Mestizos de Sangley (Chinese mestizos) would eventually refer to themselves as Filipino, which during that time referred to Spaniards born in the Philippines. The Chinese mestizos would later fan the flames of the Philippine Revolution. Many leaders of the Philippine Revolution themselves have substantial Chinese ancestry. These include Emilio Aguinaldo, Andrés Bonifacio, Marcelo del Pilar, Antonio Luna, José Rizal and Manuel Tinio. Chinese mestizos in the Visayas Sometime in the year 1750, an adventurous young man named Wo Sing Lok, also known as "Sin Lok" arrived in Manila, Philippines. The 12-year-old traveler came from Amoy, the old name for Xiamen, an island known in ancient times as "Gateway to China"—near the mouth of Jiulong "Nine Dragon" River in the southern part of Fujian Province. Earlier in Manila, immigrants from China were herded to stay in the Chinese trading center called "Parian". After the Sangley Revolt of 1603, this was destroyed and burned by the Spanish authorities. Three decades later, Chinese traders built a new and bigger Parian near Intramuros. For fear of a Chinese uprising similar to that in Manila, the Spanish authorities implementing the royal decree of Gov. Gen. Juan de Vargas dated July 17, 1679, rounded up the Chinese in Iloilo and hamletted them in the parian (now Avanceña Street). It compelled all local unmarried Chinese to live in the Parian and all married Chinese to stay in Binondo. Similar Chinese enclaves or "Parian" were later established in Camarines Sur, Cebu and Iloilo. Sin Lok together with the progenitors of the Lacson, Sayson, Ditching, Layson, Ganzon,
