Actually he already went 10 days ago with some friends to the oldest temple in Beijing (even older than the city itself) and saw some beautiful old trees, but not the usual spring blossoms. One small yulan magnolia (indigenous to central and eastern China) tree was just starting to show some flower buds. The temple has both white and the less common purple varieties.
Three other temples also have purple, white or pink lilacs in their grounds, and some are over 200 years old. Then it will be the turn of the peonies in their various colours, including black and green. And the most famous place to view the largest area of lilacs is the Temple of Heaven.
Now, in our area, we can see a whole range of colours, and even more is promised as the weather warms up.
I think the easiest piece of advice to follow is the first bit about sleeping later. Agree?
