On 3 November 2012 at 03:50, the lift No.6 was out of order. After your technician inspection, a door spring has been replaced by your technician. At 04:55, the lift has been resumed to normal operation.

However, to our disappointment, the Lift No.6 was tripped again and our staffs were trapped in the lift at 08:08.
