From the Yuan Ching Secondary School main entrance, there is a boat jetty with 2 cluster of buttress trees next to the Waterways Watch Society. The 2nd buttress tree, there is a barrow within where the black cobra resides. At all times, it was poised to strike, all raised-up with hoods open. While keeping a healthy distance away from it, the black cobra felt very easily even when there was no disturbance). It's quite aggressive. This matter had been reported to NParks.
