Through his grandmother’s referral, Ng Hung On’s parents sold him to Sai Kung for 300 military yen. In Sai Kung, Ng Hung On worked for the Tse family who was an indigenous household. The Tse family was his grandmother’s remote relatives. Ng Hung On carried out duties such as chopping firewood, herding cattle, feeding the cows at night and farming.. He worked in the fields with his elder uncles’ wives and his aunt. He had been arranged to study in a rural school (The word ‘Public’ was shown in the school’s name.)
