He requested me to borrow him ￥20000, I lent 6000. Deleted me from Wechat and didn't pay me back

Met eugene yeo(jiedong yeo) from okcupid.com. I know him for half an year. So when he said he didn't bring enough ￥ in cku competiton , and the dog show can't accept credit card to pay, then requested me to borrow him ￥20000, I lent 6000. But after the show, he deleted me from Wechat, didn't pay back. I have sent friend request to ask him, he blocked me.

As I known, he has enough money, but he just wants to scam money from others. Guess he covers well in Singapore .
