was publicly listed. In the late 1970s, Tang expanded his business again when he decided to develop the neighboring property lots which he had bought years before. In 1982, the building on Orchard Road was demolished to make way for the new Tang complex, comprising the 33-story deluxe Dynasty Hotel (now the Singapore Marriott Hotel) and the Tangs shopping complex (now Tang Plaza). The shopping complex consists of five floors of retail space covering more than 15,000 m2, marketed under the slogan "All The Best Under One Roof". In 1991, Tangs opened its first overseas branch in Kuala Lumpur, Malaysia. Tang also collaborated with Malaysia's Mayang Sari Bhd to develop real estate, hotels and commercial properties in Kuala Lumpur. He also assisted the Dairy Farm International Holdings in its retail business in Malaysia. Until 1996, Tangs was the only major shopping centre in Singapore to not operate on Sundays, in deference to Tang's Christian faith. Tang instituted the policy so that his family and Christian staff could attend church on Sundays. As a staunch Christian, Tang spoke of honesty and hard work as his guiding principles. Tang's distinctive management philosophy was the focus on people, both customers and staff. Emphasis was given to quality of the staff, reasonable pricing and warm service. Tang believed in investing in his staff, as his frontline staff would be the ones who would be in direct contact with the customers and he believed that the image of the store depended on them. As a result, Tang reserved a substantial annual budget for staff training, which included tailored programs for sales staff, supervisors and management. Supervisors and managers were expected to undergo a minimum 100 hours of training. Tang also made an effort to get in touch with his staff at all levels, in order understand his customers' expectations on product and service quality. Despite the company's poor financial results in certain years, Tangs retained its reputation for good service and reliability. Tang retired in 1987, handing the reins of corporate leadership to the second of his three sons, Tang Wee Sung. Tang retained the post of company president and was rarely out of touch with company business, personally checking the company's accounts and meeting suppliers.
