Baidu heat map shows Hong Kongers fleeing "red-light" district

Following CCTV’s recent revelation on rampant prostitution in the Dongguan province, what’s shown on Baidu’s newly launched interactive heat map was that of all the people who fled the district on Sunday, people leaving for Hong Kong topped the chart.CCTV reported a large police crackdown on Dongguan’s underground sex trade on Sunday.According to the map, among the cities which receive the most runaways from Dongguan on Sunday from 12pm to 8pm, Hong Kong accounted for more than one quarter, followed by Ganzhou, Jiangxi, Guangxi Yulin, Chenzhou, Hunan and Zhejiang Ningbo.On the other hand, those moving towards the district saw Ganzhou as the highest, followed by Chenzhou, Hezhou and Hong Kong.Updated every four to eight hours daily, the Baidu live map visualises the hottest migration routes and the most popular places travellers are heading to and leaving from.The data was generated by Baidu Maps app users who use their GPS coordinates.Although the fleeing figures may have prompted a surge of Chinese sex workers into Hong Kong, there is no concrete evidence to support this.During the CNY festival, the map tracked 1.3 million people travelling into the countryside, which the search giant claimed to be the largest annual human migration on earth.
