History

On January 8, 2015, the Transport Department presented proposals to the Kwun Tong District Council’s Traffic and Transport Committee for public transport services in the. These included six new routes, four of which were to be awarded through open tender, including a bus route circularly connecting the development area to Lam Tin MTR Station to facilitate MTR access. The proposal noted that the route would initially use On Tat Estate as a temporary terminus, moving to On Tai Estate once it was occupied.
In November 2015, the Transport Department awarded operating rights for all four new routes to KMB, designating the route to Lam Tin MTR Station as 213M. With On Tat Estate gradually occupied from 2016, the route commenced service on June 4, 2016, initially operating circularly between On Tat and Lam Tin MTR Station, offering a HK$0.6 MTR transfer discount. On August 6, 2016, an additional stop was added for the On Tat-bound direction outside the Kwun Tong Police Station on.
As On Tai Estate began occupancy in mid-2017, concerns were raised by On Tat Estate residents and the On Tat Residents Association’s secretary-general,, about potential boarding difficulties if 213M’s terminus was extended to On Tai. The Transport Department responded that adjustments would consider On Tat’s needs, potentially including special services during peak hours to ensure both estates’ residents could access bus services. On June 29, 2017, 213M extended its terminus to On Tai, adding a stop near Oi Tat House at On Tat Estate on On Sau Road for both directions, bypassing On Tat Terminus for On Tai-bound trips. Simultaneously, the special service 213S was introduced, following the pre-extension 213M route during weekday morning peak hours. The HK$0.6 MTR transfer discount was extended to 213S, but both routes’ discounts ended on October 1, 2018.
Citing congestion in Kwun Tong Town Centre, the Transport Department initially resisted introducing direct public transport to the area. However, on March 1, 2019, the Transport Department proposed to the Kwun Tong District Council adding a special service 213B for 213M, offering five morning weekday trips from On Tai via On Tat and Hip Wo Street to Tung Yan Street in Kwun Tong, returning via Tseung Kwan O Road. Route 213B began service on March 25, 2019. From April 14, 2020, 213B was temporarily reduced to four trips, a change made permanent from August 9, 2021. From August 14, 2023, all 213B trips were rerouted after to travel west on Kwun Tong Road, adding a stop at Millennium City before terminating at Ting Fu Street, without returning to On Tai. From December 15, 2024, 213M added a stop at Kam Tai House on On Sau Road for On Tai-bound trips.
