Usual stamps with "Longhorn beetle" pattern

OH NO~~

This afternoon, I go to the post office for chasing some stamps.
今天下午我去郵局買郵票

I need some small face value stamps.
我需要一些小面額的郵票

Then I ask the counter.
向櫃檯詢問

I think there are more than one pattern I can choose,
but the lady tells me a bad news only one is "Longhorn beetle".
我認為應該有不同的圖樣可以選吧
但是那位小姐跟我說了一個壞消息 只有"天牛"這種喔

SHOCK!!!

Because I really need it, the result is...............
因為我很需要小面額郵票，因此就........

I can be sure that you guys must get this kind stamp if you receive the postcard from me.

我可以說你們若是收到我寄的明信片，肯定是天牛圖樣的

Please don't blame me. I have no choice. (sad)
別打我，實在沒得選阿(哭哭)
