They have hired volunteers, dressed in yellow shirts, to fill up empty venues and improve the atmosphere inside.
A Chinese spectator said, There were heaps of empties, it's sickening.
One official said, some spectators were also only turning up for specific events, even though they had tickets for a whole session.
Another explanation for empty seats:
For competitions like beach volleyball and basketball, [spectators] have one ticket for the whole afternoon, morning, evening. They may choose to go to one of them, but not all them.
Mr Wang, executive vice-president of Bocog, said local authorities were hiring volunteers to fill empty seats.
“If they find that there are not enough people, or if they find that there are too many empty seats, they organize some cheerleaders," he said. These cheer for both sides to "create a good atmosphere", he added.
