 In 1821, the Hainanese arrived in Singapore to trade medicinal herbs, umbrellas and wax amongst other things.They did not immigrate to Singapore until much later in the 1870s due to conservative attitudes and delayed open trade and seafaring activities.This left the Hainanese at an employment disadvantage compared to earlier arrivals like the Hokkien, Teochew and Cantonese, whom had already entrenched themselves into industries like commerce and agriculture, due to aid from exclusivist clan associations.
