China's other major weapon is their fanatical support, though fewer than expected have actually made the trip to Korea.
The tiny island of Jeju, where China face Brazil on Saturday, had braced itself for an island invasion.
What they got instead was a fairly hectic package holiday booking.
The Korea National Tourist Organisation predicted a total of 90,000 Chinese visitors during the World Cup.
Of those, only 65,000 were expected to attend matches, with the remaining 25,000 regular tourists.
But that figure may turn out to have been over-optimistic.
"We can hardly find any special increase in tourism during the World Cup.
"In particular, the Chinese have complained it takes too long to get a visa for Korea," said a travel agency spokesperson in Korea.
But those who have made it here have been impressive in their support.
And, after the co-hosts, China are still the best-supported team in the competition.
Known as Chiumis - or soccer worshippers - China fans are similar to Korea's Red Devils in their fanatical support.
About 6,000 Chiumis were among the 27,217 crowd in Gwangju to see China beaten 2-0 by Costa Rica.
And even more are likely to create a red carpet welcome when the team arrives in Jeju.
If they all believe hard enough, then miracles might just start to happen.
