We just found out that the Mafia has its own Ten Commandments, so it's no surprise that the people of Shanghai also have their own list of "Seven Don'ts"
For those who're too lazy to look 'em up:
expectoration: spit
attaint: disgrace, bring dishonor upon, condemn.
virescence: state or process of becoming green. I assume they mean greenery here.
