I obviously turned off the location function in the privacy of my mobile phone. Why can Sina Weibo still locate my position?

So is mine. The advertisements pushed are all related to geographical location. One minute in college, one minute in plastic surgery. It's all my local content and advertisements on the home page. That's disgusting.

As for the reason, I think it should be that app exchanges information. Taobao and Weibo have a cooperative relationship. Taobao will definitely open its position, and Weibo will know that privacy is a joke in the era of big data. Baidu searched what Taobao pushed, and even said what it wanted to eat in the dormitory. If you are hungry, Meituan will push what you want.
