During the Vietnam War, Hong Kong was a favoured place for R&R (rest and recuperation) for American soldiers, and before them, the sailors got boozed-up in Wan Chai district in downtown Hong Kong. Like other R&R places (like Singapore, Tokyo and Taipei) Hong Kong has pulled its act together. Today, the bars in Wan Chai are mostly drinking pubs with the occasional bargirl, while the red-light district has moved to other parts, like Mong Kok across the bay, and has become less obvious. The only thing you see from the street are signs offering girls of any colour.
