Shanghai-born entrepreneur Zhang Runzi rallied 56 employees from her vacuum cleaner retail business to support PAP candidate Mr Sam Tan. They chanted “Sam Tan bi sheng” (Sam Tan must win) and “PAP bi sheng” a few times. Ms Zhang, 42, a mother of three, has been a Singapore citizen for 16 years. She chartered a bus and gave her staff half the day off to support the PAP, which she thinks has made Singapore a happy and prosperous society.
