Following the earthquake, many San Franciscans relocated to Oakland, including several Chinese. As with several ethnic groups, Chinese were compelled to remain in ethnic clusters. Lew assisted these Chinese with finance and leadership by organizing neighborhoods, including the area that became Oakland's Chinatown. As a consequence, he became involved with many Oakland Chinatown organizations, making contributions to their many causes and forming business alliances in relation to the Pacific Canning Company. As the Pacific Canning Company prospered, Lew Hing diversified his interests into many other areas, including a personal interest in the Loong Kong Tien Yee Association, an organization for the families of Lew, Quan, Jung and Chew, and fostered the group in both Oakland and San Francisco.
