It's all to do with female hormones. Generally speaking, young Chinese women who reveal too much of their physical attributes in public by wearing scanty clothes know full well they're beautiful and are seeking love and boyfriends. And there are lots of such dishes to be seen outdoors here. I reckon back in Blighty they would turn the heads of many a young British male if they walked the streets. You can just imagine the wolf whistles such Chinese beauties would instigate back home in public places.
Most British girls are no match for them in the good looks department.
As for 'Blubber Belly', I can understand why he loves China. There are mch worse ways for him to spend his money than on stick insects! And he's contributing to the local economy by doing so. Good luck to him!
