Bailu, which will fall?on September 7, 2008,?reflects
a weather phenomenon. Around the day of Bailu, the temperature
declines gradually. It is still warm in daytime but cold at night,
causing the formation of dew. When the dew accumulates, it becomes
white in color?-- white dews.
Weather:
There is typically autumn weather during Bailu period, when wild
geese begin to migrate to the south and birds start to stock food
for the long winter time. Hot summer is gone. However, it could be
still warm in south China. It is different in the Yangtze River and
Huaihe River valleys where it is usually humid during this period,
as the saying goes: "It's unusual to see ten continuous sunny
days." The reason is that at this time cold wind blows southward
from the north, while warm and moist wind comes from the south, and
they meet in the region, resulting in the rain. The locals call it
Bailu rain, which is important for the growth of autumn crops in
the region.
Lifestyle:
This is also the season that people may be exposed to various
diseases like nasal disease, asthma, and bronchitis. Too much
seafood or cold, spicy, or greasy food may not be good for health,
but food containing more vitamins is good for your diet since the
weather is getting drier after Bailu.
