[Repairing] Since last time we fix our heater, we decided to repair the restroom sign, which was declared dead by the electrician, who said there is no replacement and need to change the whole set. Well, I just don't believe that.
After couple of thoughts, we went to Zhonghua road (中華路) to buy a 5m blue LED, and one transformer and started to repair it by ourselves. BOOM, there you go. A shiny new sign has reborn.
