Retell
the
conversation.
We
compared
different
aspects
of
China
and
the
U.S.
For
history,
with
a
history
of
more
than
5,
000
years,
China
is
one
of
the
oldest
countries
in
the
world,
while
America,
with
a
history
of
less
than
300
years,
is
one
of
the
youngest
countries
in
the
world.
We
can
see
China
is
much
older
than
the
U.S.
As
for
population,
China
has
the
biggest
population
in
the
world.
It
is
a
lot
bigger
than
the
population
of
the
United
States.
In
terms
of
the
area,
China
is
the
biggest
in
Asia.
And
China
is
about
the
same
size
as
the
U.S.
As
for
rivers,
the
longest
river
in
China
is
the
Yangtze
River.
It
is
6,300
km
long.
Besides,
the
Yellow
River
is
5,464
km
long.
The
Yangtze
River
is
as
important
as
the
Yellow
River.
These
are
the
differences
and
similarities
between
China
and
the
U.S.
