Mountain fire smoke causes air index exceeding 200 Australian Open players to have difficulty breath

On January 14, the 2020 Australian Open kicked off. Frequent mountain fires and thick smoke caused Melbourne's air quality index to exceed 200 during the competition. After the start of the competition, YAKUBOVICH, the leading player, suddenly had difficulty breathing. She knelt on her knees and coughed bitterly. Finally, she had no choice but to quit the competition. Tennis star Sharapova also ended the performance match early due to air problems.
