Help with Chinese note/billet [opgelost]

Hi,
Today I've got 4 notes; a Hungarian 100000 Pengö (one of the stamped in 1945), a Cambodian 50 Riels, a Chinese 1 Jiao ...and this:

Obvioulsy Chinese, but not an official banknote (that I've checked, nothing at Colnect)

Any help with the ID is appreciated, it just requires someone that can read chinese.
Thanks in advance.

It sounds like a rationing ticket.

Curiosity, what's written on the back side?

And thanks for the quick answer!

​Thank you!

And case closed!
(But how this ticket ended in Brazil? I'll never know.)

According to personal knowledge, the largest foreign Japanese community in the world is in Brazil.

So maybe, somehow the Chinese gave the Japanese, they moved to Brazil and ended up in the markets.

​Indeed we have the largest Japanese community outside Japan, but we also have Chinese and Korean communities. Maybe it came with them.

Here is a site with a lot of these food coupons pictured.

在中国省以下的市级发行的粮油票可以兑换相应数量的物资。我也有。因为我是中国人，所以我对现代和现代硬币有一点了解。任何问题都可以帮助您解答。
