Translating a US Thanksgiving to family in China

"Well, we have this big meal together with family, and we eat things like turkey and cranberries ..."

As I tried describing Thanksgiving Day, one of the most quintessential holidays in the United States, to my in-laws in China, I could already see their eyes glaze over with confusion and sense the questions forming in their minds. Turkey? Cranberries? Even though I expressed these perfectly in Chinese, the result was still gibberish because they had never seen a turkey or tasted cranberries.

So I attempted to translate the holiday through more familiar Chinese counterparts.
