he green corridor is formed by hundreds and thousands of old cypresses.Grassroots called
them imperial cypress.It is said that zhangfei called for people to plant them when he wasappointed
to defend Langzhong so these cypresses are also called zhangfei cypress. According to historical in-
formation and sagas,these old cypresses are shaped by a few generations ,theexact time of their pla-
nting can be traced from qinhan to mid-term of ming dynasty more than2000 years ago. As the extensi-
on of old road and restoration of avenue goes by,there remains natural plants and a lot of trees pla-
nted by men,Gradually, the great boulevard appeared。

CuiYun corridor name after the poem of QiaoBo who was the leader of Jianzhou in qing
dynasty:Jianmeng road is very uneven filled with stones.for whom these old cypreare planted? These t-
rees are planted densely and largely.Cui Yun corridor is shielded by smog.You feel comfortable when
you walk in a drizzling day because you can feel cool breeze and wet clothes. When you are tired ,you
can rest on any big stone When you feel pleasant and want to write something suddenly , you can write
down it everywhere. All the paths and mountains tangle together looks like snakes and dragons twine
together. Do not think shudao very steep; Do not miss the chance to experience jianmeng road. Later on ,
Jianmeng road cypresses got its poetic and wonderful name-CunYun corridor。
