first korean to be in the grand slam tennis tournament!!

Today, a Korean tennis player played with an American tennis player to go to the semi finals and win the Grand Slam tennis tournament!!! It is the first man in Korean history to go up this far. A Korean person who is 21 years old named Jeong Hyoun is the first to have hope to go to the semi finals in the tennis tournament that is happening in Australia. In the last round, he won and bowed to his mother, father and his older brother because of helping him to go this far in this world wide tennis tournament. I really hope that this Korean person will go to the semi finals and beat tennys sandgran. infinite chears to this Korean person!!!!!!!!
