Hawker centres not only offer a diverse range of local delicacies, but also reflect Singapore's multiculturalism.

By introducing better facilities, such as free Wi-Fi and holding community events there (Hawker centres to get new look and roles; Feb 4), the food centres will become more attractive to both locals and tourists.

Centralising processes, such as dishwashing, and having equipment that automate repetitive tasks will greatly reduce manpower costs and attract more to join the trade.

The incubation stalls are a good way to allow young people to try out the profession and, hopefully, encourage more to join. Perhaps an attachment programme could be introduced for young people to work with existing hawkers.

More hawker centres should adopt the radio frequency identification tray-return system already in place at Timbre+ food centre in one-north (It pays to return your tray - and it's easy too; Sept 7, 2016). The main aim of reinventing hawker centres should be to retain their rich culture yet introduce new and creative ideas to ensure their sustainability in the long run.
