How to write Yuan-day couplets?

Yuanri is a seven-character quatrain written by Wang Anshi, a politician in the Northern Song Dynasty. This is an impromptu work about welcoming the New Year in ancient times. Based on folk customs, it absorbs the typical materials of ordinary people during the Spring Festival and captures the representative details of life: setting off firecrackers, drinking Tu Su wine and changing peaches, which fully shows the happy atmosphere of the Spring Festival and is full of rich life breath.
