" Say, cross my heart straight dinkum" .

“说吧，直直地穿过我的心”。

Or you can basically hear the snot running out of the noseand the tears running out of the eyes, that's when you know, people are being fair dinkum, that's when you know that they're being real.

基上到鼻涕从鼻子里流出来， 眼泪从眼睛里流出来，那时候就知道， 人们是公平的，那时候就知道他们是真实的。
