I bought frozen BBQ eel and the best before date says LJ349. What does this mean? - Lemmy.World

I looked around the packaging for other clues as suggested by another Lemming but I didn’t find anything. In fact I found the same thing printed on the front.

On a Chinese food package, β€œBest Before LJ349” typically refers to the expiration date, although the code β€œLJ349” doesn’t follow a standard date format. In this context, β€œLJ349” is likely a batch code or internal reference used by the manufacturer. The manufacturer uses this code to track production specifics, such as the location or production line and date.
Thanks GPT, very useful
I thought it was helpful in the sense that there’s likely no way to relate the date code.
I mean, you could have just said that instead of the unhelpful bullshit GPT apparently put out. Or just not commented at all if you didn’t actually have anything helpful to add.
Meh, I thought it was useful, maybe next time I should attribute GPT. No need to get bent up over it. It did attempt to give extra information that wasn’t in the thread at the time.
It’s Japanese not Mandarin too. I see うγͺぎ - unagi, which is definitely Hiragana
It's not a loan word so it's written in Hiragana.
Ah, fair! I only very recently started learning some Japanese, so beyond hiragana and katakana, I recognize basically nothing. I absolutely wouldn’t be able to recognize the others as Cantonese!
