In the face of Sindu, who is good at attacking, Zhang Peiwen played the power of his four-sided ball, and combined with the assault and killing, she won two straight sets, 21-12 and 21-18, and was promoted by surprise. In the semi-final, Zhang Beiwen will compete with world champion Indanon for a final seat. If she can win again, she will return to the top.
