Erasmo Wong is a Peruvian descendant of Chinese immigrants and former owner of the Wong supermarket chain. He studied at the Anglo-Peruvian School (Colegio San Andrés). Wong's growth was characterized by going against market trends, being more customer service oriented instead of the more usual self-service and investing during some of the Peruvian economy's hardest times.
While Wong focuses on bringing customers product variety and a highly personalized service, the Metro hypermarket chain offers lower prices and self-service stores.
