When the last leaves of autumn fall; when the thin mist of early morning fly on the Hoan Kiem (Sword) Lake; it is the time Hanoi enters winter.
For Hanoians, Hoan Kiem Lake has its own beauty every season. In the winter, when thick fog remains until 7-8am, there are pictures of poetic Hoan Kiem Lake.
In the early winter, leaves begin falling from the trees around the lake.
The scene is somewhat mysterious as fog is still thick.
Some red leaves of mangobarks and bang lang still remain.
