Flowery month.

If you bothered to notice while travelling, you'd see trees blooming with flowers.
In CCK, in the forests are the red flowers high up on the trees.
Around Bouna Vista and Queensway are the pink flowers that are reminiscent of Sakura, looking especially lovely with pink strewn all over the adjacent grass patches.
The rest would be the yellow flowers of some tree I know nothing much of.
My trusty Nokia Lunar Calendar states Er Yue Chu Wu ( 5th day of 2nd month ), so checking out the next bloom would be my natural instinct. Haha.
When it comes to agriculture and plants, I like to refer to Lunar calendars, I just have this simple faith that ancient Chinese done superb research on plant biology and weather.
