its centenary on its founder's day, 21 March 2019. On 21 March 2019, in commemoration of the school's centennial, a dinner dubbed the "dinner of 10,000 people". It was celebrated in the field before the school's iconic clock tower and the statue of Tan Kah Kee, the school's founder. The celebratory dinner entered the Singapore Book of Records as the largest school anniversary dinner, with 12,581 attendees, including Prime Minister Lee Hsien Loong. This was the fifth time Hwa Chong had organised such a celebratory dinner, with prior dinners in 1979, 1989, 1999 and 2009. The same year, the school staged the Centennial Musical at the National University of Singapore Cultural Centre. The musical featured 537 participants, and was attended by alumna Sim Ann, Senior Minister of State at the Ministry of Communications and Information. The Singapore Symphony Orchestra's Tan Wee-Hsin was the conductor, while Yang Wenzhong was the director at-large with the orchestra comprising HCI students. School identity and culture Uniform and attire In the High School Section, students in Secondary 1 to Secondary 3 (inclusive) wear a white short-sleeved shirt with khaki short trousers and white socks, which must cover the ankles. The four metal buttons must be worn on the two front pockets and on both shoulders. The school collar pin should be worn on the left collar. Either white, blue or black shoes with either white or black laces must be worn. Secondary 4 students wear beige long trousers with a beige shirt, similar to the boys in the College Section. College girls wear a beige blouse and a beige skirt. The uniform for the College Section is the same as that of the former Hwa Chong Junior College, and it was designed by a Malay girl of the pioneer batch. Discipline Students earn demerit points for poor behaviour. Accumulated demerit points can affect final grades and eligibility for certain awards, scholarships and overseas trips. The student handbook for the High School Section states that students who commit serious offences may be punished with detention, caning, suspension, or expulsion. Only the principal or discipline master may administer caning. Students found smoking are immediately caned or suspended or both. Caning may also be given for integrity-related offences (e.g. cheating), uncivilised behaviour (e.g. defiance), and criminal offences (e.g. fighting).
