Context: The collector was interviewing the informant (as MD, the collector’s mother) for folklores. After she told the collector a folklore about eggs, the informant came up with another folklore about eggs. This is a custom the informant practiced in her childhood.
MD: When I was a kid, we (she and her peers) would have hard boiled eggs on Duanwu Festival (Dragon Boat Festival). We would weave nets to hang an egg on our neck. (Collector’s note: The nets were made of colored thick thread which was thinner thread intertwined together, according to a follow-up interview). Ah, that was really interesting. Every girl at that time could weave nets.
Collector: Is there something to do with good luck or stuff?
MD: I don’t know. We just followed what adults told us.
Collector: So what did the custom mean to you?
MD: That meant we could eat (eggs)! Those were eggs! It was just, like, whenever it was Duanwu, we could have eggs. (Collector’s note: eggs were not food that could be served every day for most ordinary Chinese families in the 1960s and 1970s.) After we hung the eggs in the day, we could eat them.
Festivals are time to have foods that are not available all the time.
The interview also indicates the social environment and the financial status of ordinary families in 20th century China.
During the interview, the collector recalled a prose written by a Chinese writer, Zengqi Wang, that was exactly about eggs on Duanwu. Wang’s hometown is Gaoyou, a city in Jiangsu Province, which is also in the Yangtze River region like Shanghai. However, the eggs mentioned in that prose was duck eggs. See:
