China thrashed India 5-0 in the Sudirman Cup on Sunday, but the defending champions were given a tough workout by their unfancied opponents while Taiwan managed a surprise win against Malaysia.
So distraught were the Chinese officials over their players' lacklustre performances in their opening Group A match that they snubbed the official press conference after their tie.
The eight-time winners of the trophy, who are gunning for their fifth consecutive crown, took more than three hours to subdue their opponents to virtual guarantee themselves a place in the quarter-finals.
The third team in Group A are former champions Indonesia, who play India on Monday.
With only three teams in each of the four groups, the top two countries will qualify for Thursday's quarter-finals.
More worryingly for China was the form of world champion Wang Yihan, who was stretched to three games by upcoming Indian star P. V. Sindhu. Sindhu was playing in place of the injured Saina Nehwal.
