I'm interested in the picture on the linked webpage above
On the yellow board, the following letters are written.
"
俄羅斯??
RUSSIA 590
中國大陸
CHINESE 280
香港本地
HONG KONG 280
馬拉泰國
Malay Thai 250
"
At first, I guessed these numbers indicate the prices of having sexual intercourses with each nation's woman.
But, when I consider that prostitutes get US$40 per hour, these prices are too cheap on the assumption that these prices are based on Hong Kong Dollar.
I wonder what the board indicates.
