How can I own qq yellow diamonds for free?

Alas ~ ~ `Now the code seems useless ... eh? ~' Almost all'' But there is a good way to brush yellow diamonds for free ~! !

Send a text message with your mobile phone (check what to send and where to send it), get what you want after you get the yellow diamond, send a text message to return the yellow diamond, and you will have what you want ... Hoo-hoo, very useful ... but there may be other surprises, maybe Tencent sometimes ignores it ... and gives you a permanent yellow diamond,,, and JJ will get a permanent yellow diamond for free.
