After the war, the school was turned into a soap factory, but Mr Chua Cheok Sar came to the rescue and with the support of sponsors, rented four classrooms from the factory in 1946.   Later, the Company vacated the premises.  In 1964, Mr Chua, the founder, passed away.  Sing Hua became an aided school in 1957 with an enrolment of more than 500 pupils.

         In 1964, funds were raised for a new building.  The foundation stone was laid in 1971 and in 1976, the school was officially declared open by Mr Sia Kah Hui, the Minister of Labour then.  It was a Chinese-English Integrated School.
 
 

       Mr Chua Tiah Seng served as Sing Hua's principal after the war. He was  succeeded by the Senior Assistant, Mdm Ching Siew Chin in 1976.  It became a government school in 1983.
 
 

         The school moved to  Hougang Avenue 1 on 17 December 1984 and received the present pinyinnised name, Xinghua Primary School, with English as the medium of instruction.  Mr Vincent Sim took over as principal in December 1997 as its seventh principal.
 
 

           On 15 December 2000, the school shifted to 30 Parry Avenue  to facilitate the construction of a new building at Hougang Avenue 1. Mrs Woo-Mah Yoke Yoong took over from Mr Vincent Sim as the eighth principal of Xinghua Primary School.

           The old building in Hougang Avenue 1 was totally demolished and a  new school was built on its site. In January 2003, the pupils and staffs of both Xinghua Primary School and Charlton Primary School merged when the school shifted back to its present location at Hougang Avenue 1. Ms Susan Lim Poh Suan took over from Mrs Woo-Mah Yoke Yoong as the ninth principal of Xinghua Primary School.
