Basically, they are liars. Jiayuan is now a more advanced liar. I used to register for a new QQ. Now I use QQ registered for many years to communicate with you. Finally, they always sell you direct sales, silver, futures, foreign exchange and even pyramid schemes, intentionally or unintentionally. Making friends is the first priority. You must have your own standards and requirements when choosing friends. Don't think things will fall from the sky.
