Wang revealed that she didn't have a coach and legitimate training due to the pandemic.
Both Thiem and Zverev are seeking their first ever Grand Slam title, and Thiem might have a slight mental advantage, winning the past three matches against the German.
Huesca did tremendously well under coach Michel to bounce back to the top-flight at the first attempt last season and newly promoted sides often start with a surprise, but on paper Villarreal should be much too strong for them.
Evergrande had a good opportunity just four minutes into the game but Ai Kesen hit chance off target.
Shaanxi failed to level up before the half-time break when Wang Erzhuo's powerful long volley out of the box went wide in the 30th minute.
Title favorite Qingdao stormed to a 3-0 lead in the match against Shenzhen. Chen Yufei then fought for 49 minutes to overtake Zhang Yiman 7-11, 11-6, 8-11, 11-5, 11-6 in a tight game of women's singles, before Zheng Siwei/Liu Yuchen took a straight win over Liang Weikeng/Wu Tuobin in the men's doubles, adding the other two points for Qingdao.
"My right eye was uncomfortable before the game, and I was influenced by that when I played. I was not in form today, but Ren played well," said the world No. 5 Chen.

"I knew to keep calm and wait for the right gap to open - and it did, quite late."
