Besides returning immigrants, starting in 1960, Lin Fa brought nearly 1,000 Taiwanese to the island under the name of "technical advisers" for pineapple planting. Although these people have never set down roots to become immigrants, they have permitted Taiwanese to maintain their strength and influence on Ishigaki.
回流移民之外，從一九六○年代起，林發又以種植鳳梨所需的「技術導入」的名義，陸續引進近千名台灣人，這些人雖未落地生根成移民，卻也使台灣人在石垣島的聲勢及影響力一直維持著。
