The word "warm wind" is a pun. In poetry, it refers to both the spring breeze in nature and the lewd wind in society. In the poet's view, it is this "warm wind" that blows the minds of "tourists" so intoxicated that they forget that their country is in danger.
The word "smoked" symbolizes the huge lively scenes of those songs and dances, creating a decadent atmosphere for "tourists". Then the word "drunk" is followed by the word "smoked", which vividly depicts the mental state of those "tourists" who indulge in debauchery.
In order to further show that "all tourists are drunk", the poet wrote at the end: "Let Hangzhou become Bianzhou." The capital of Song Dynasty was originally located in Bianliang, but it was occupied by gold. In other words, among the fans, these "tourists" simply regard Hangzhou as the old capital Bianzhou.
