The Temple of the Premier of Shu

Where is the temple of the famous Premier? —
In a deep pine grove near the City of Silk,
With the green grass of spring colouring the steps,
And birds chirping happily under the leaves.
. . . The third summons weighted him with affairs of state
And to two generations he gave his true heart,
But before he could conquer, he was dead;
And heroes have wept on their coats ever since.
