汇票

It is a bill payable at sight.

那是一张见即付的。

Can you cash this postal order for me now?

现在能帮我兑现这张邮政吗?

You need an official signature to validate the order.

要有正式的签字,这张才能生。

"An indorsement in blank specifies no indorsee, and a bill so indorsed ecomes payable to bearer."

无记名背书并不书明被背书人，以此方式背书之，应成以持人人之。
