In fact, the word "grand slam" was never used from the beginning. Strictly speaking, the Grand Slam and Grand Slam only appeared in 1993, because it was determined that the top tennis event was the Australian Open, followed by the French Open, Wimbledon and the US Open. The real Grand Slam winner was Donald Buji in 1938, who won the men's singles championship in the US Open for many years in a row.
The difference between tennis grand slam and grand slam
The difference between a grand slam and a grand slam lies in the number. A grand slam means that an athlete wins all four top tennis championships, and a grand slam only wins one of them.
At present, there are very few athletes who have won the Grand Slam. Only Donald Buji and Rod Laver are men's singles, while Maureen Connolly, margaret court and Stiffi Graff are women's singles. There is also a Grand Slam in China, where Li Na was once very famous.
