Rothary and Simone Dimang at their Donut Shop Most American immigrant stories include finding success in one particular business niche with which the group becomes identified. For Cambodians, it has been doughnut shops. These kinds of small businesses worked well for Cambodians because they could be run by families and did not require extensive English language skills. Pictured is Rothary Dimang (center at the counter) at his shop on Pine Ave and Fourth St in Long Beach, CA, which he ran between 1983 and 1985. To the left is Simone, his wife. Behind him are other family members who helped in the shop.
