Spring rolls' New Year symbolism is the most visually immediate of any festival food: pull a freshly fried spring roll from the oil, and you hold something that gleams gold — the exact color of wealth, of ingots, of the treasure associated with New Year prosperity wishes. Place a platter of them on the table and you have, quite literally, arranged a display of golden bars.
The name reinforces the connection: spring rolls are named for the Start of Spring (立春, lì chūn), the solar term that marks the first day of spring on the traditional Chinese calendar. Eating them celebrates the arrival of spring — renewal, new growth, and the beginning of the agricultural year. At New Year, spring rolls embody both the gold of wealth and the freshness of new beginnings.
