I've tried my
socks off, but no good result!

Taking your socks off was a suave move; you shouldn't be 'reddened by the event'.
If, as I suspect, you are actually of Chinese ancestry, you should remember that China's red light industry, though significantly diminished in the past decade, has a long history and a cultural prominence far more significant than that of any Western country.
FT patronage of prostitutes in China is of little consequence in a country where wealthy men and corrupt bureaucrats writhe in saunas, grope in Xiaojie KTVs, and keep Xiaosans.
