What are the advantages of handwritten calligraphy couplets over printing? The advantages I want to say are: (1) The content of couplets is convenient and free, and you can choose your favorite content to the greatest extent; (2) Excellent family cultural accomplishment; (3) Adding a festive feeling, writing by one person and watching by the whole family is enjoyable and beyond words. Of course, the benefits are not limited to these and cannot be repeated. Think about it, am I right?
