This is poem 69 at Angel Island. The translation by AIISF is
Detained in this wooden house for several tens of days,
It is all because of the Mexican exclusion law which implicates me.
It's a pity heroes have no way of exercising their prowess.
I can only await the word so that I can snap Zu's whip.
From now on, I am departing far from this building.
All of my fellow villagers are rejoicing with me.
Don't say that everything within is Western styled.
Even if it is built of jade, it has turned into a cage.
