Goodbuy Winter! 100%Cotton Knitwear $40 This is an advertisement for sale of winter clothing at a reduced price. Literally, it means a good deal with good quality and low price. But when readers read Goodbuy and winter together, they understand that the advertisement has hidden secrets and witty puns. It seems to indicate to people: the cold winter is about to pass, and the bright spring is coming (Goodbye winter!). Our company is conducting seasonal sales, reminding people that this is the best time to buy high-quality and low-priced goods, don't miss it. The author takes advantage of the homophony of Goodbuy and Goodbye to make the same pronunciation imply two meanings: one refers to a good deal and the other refers to saying goodbye (cold winter). Killing two birds with one stone, it is far-reaching and thought-provoking.
