The marriage between U Kar Kar and Daw Sein signified the beginning of a new family, and a new business. With outstanding work ethic and a strong sense of family, the couple founded U Kar Ka Daw Sein, a green tea business while raising 10 children. It was one of their children, Daw Kyin Than, who inherited the company, and one of their grandchildren, Daw Nyo Nyo Sein, who manages it today. Although U Kar Ka Company started out as a small family business, it exists today as an organization with over 150 employees. Throughout the ages, U Kar Ka Co Ltd. survived World War II, a radical political transition of the country, and the fast paced socioeconomic changes of the 21st century. It has done so by embracing innovation and integrity while maintaining its culture and tradition. Today, it is a well-respected brand and a market leader in the Myanmar tea industry.
