My
name
is
Wang
Kun.
Ever
since
middle
school,
my
sister
Wang
Wei
and
I
have
dreamed
about taking a great bike trip. Two years ago she
bought an expensive mountain
bike and
then she persuaded me to buy one. Last year, she
visited our cousins, Dao Wei
and Yu
Hang at their college in Kunming. They are Dai and
grew up in western Yunnan
Province near
the Lancang River, the Chinese part of the river
that is called the Mekong
River
in
other
countries.
Wang
Wei
soon
got
them
interested
in
cycling
too.
After
graduating from
finally got the chance to take a bike trip. I
asked my sister,
Mekong
River from where it begins to where it ends. Now
she is planning our schedule for
the
trip. I am fond of my sister but she has one
serious shortcoming. She can be really
stubborn. Although she didn't know the
best way of getting to places, she insisted that
she
organize the trip properly. Now, I
know that the proper way is always her way. I kept
asking
her,
looked at a map
yet. Of course, she hadn't; my sister doesn't care
about details. So I told
her
that
the
source
of
the
Mekong
is
in
Qinghai
Province.
She
gave
me
a
determined
look
—
the kind
that said she would not change her mind. When I
told her that our journey
would begin
at an altitude of more than 5,000 metres, she
seemed to be excited about it.
When I
told her the air would be hard to breathe and it
would be very cold, she said it
would
be an interesting experience. I know my sister
well. Once she has made up her
mind,
nothing can change it. Finally, I had to give in.
Several months before our trip,Wang
Wei
and I went to the library. We found a large atlas
with good maps that showed details of
world geography. From the atlas we
could see that the Mekong River begins in a
glacier
on a Tibetan mountain. At first
the river is small and the water is clear and
cold. Then it
begins to move quickly.
It becomes rapids as it passes through deep
valleys, travelling
across western
Yunnan
Province. Sometimes
the river becomes a
waterfall and enters
wide
valleys. We
were
both
surprised
to
learn
that
half
of
the
river
is
in
China.
After it
leaves China and
the high altitude, the Mekong becomes
wide
，
brown and warm. As it
enters
Southeast
Asia,
its
pace
slows.
It
makes
wide
bends
or
meanders
through
low
valleys to the plains
where rice grows. At last, the river delta enters
the South China Sea.
