It was held earlier this month in Hunan province, in a mountain range thought to have inspired the floating mountains of Pandora in the Hollywood blockbuster film Avatar.

Ajinkya Rahane became the fifth Indian to score centuries in both innings of a Test match as they declared on 267-5.
In reply, captain Hashim Amla (23 not out) took 46 balls to score a run, as South Africa made 72 in as many overs.
A 300-plus target has been reached just once on Indian soil, when the home team struck 387-4 to defeat England in 2008.
India resumed 403 runs ahead on 190-4 but skipper Virat Kohli added only five runs to his overnight 83 before a low Kyle Abbott delivery trapped him leg before to end the only century partnership of the series at 154.
Rahane, the only centurion of the series, was not to be denied another hundred, however.
The 27-year-old slog-swept Imran Tahir over mid-wicket for his second six of the innings and flicked Dean Elgar for another to move into the 90s.
He joined Vijay Hazare, Sunil Gavaskar (three times), Rahul Dravid (twice) and Kohli as the only India batsman to reach three figures twice in the same Test match.
South Africa blocked resolutely after left-hander Elgar was caught at slip in the fifth over, with India spinner Ravi Jadeja conceding only 10 runs from his 23 overs.
The usually destructive AB de Villiers maintained the team tactic, using 33 balls to score his first run.
His partnership with the captain did not produce a single run in the first 10 overs, but both batsmen survived to retain their team's hopes of avoiding defeat.
A 3-0 series victory for India would put them second in the world rankings behind the South Africans, who will lose top spot if they lose their next Test series at home to England, which begins on 26 December.

Dr Barry Morgan, who has been at the head of the Church in Wales for nearly 14 years, is set to retire on 31 January - his 70th birthday.
During that time he has supported numerous causes, including gay marriage and more powers for the Welsh Assembly.
But he said he still believes the law introducing presumed consent for organ donation was the "wrong way".
Under the law, adults are regarded as having consented to organ donation unless they have opted out.
"I think what I did object to was people thinking that I was against organ donation," he said.
"I wasn't against organ donation at all, I was just against the method by which they were going about it.
"And I still feel that to be honest because it's much better if people voluntarily say 'we want to give organs'. That's what a gift actually means."
He has also backed women clergy during his leadership and carried out the consecration of the Church in Wales' first female bishop on Saturday.
"I think that was pretty important as a matter of justice, as a matter of equality and as a matter of doing what was right," he said.
"That's been pretty important and I never expected a woman bishop to be elected in my time."
On gay marriage, Dr Morgan has previously called for the church's view on same-sex marriage to change with popular opinion.
"I haven't done that on my own. I've done that with the full support of the present bench of bishops and also with the support of the governing body," he said.
"That's quite something, I think, in a church that hasn't always been known for its liberalism."
He admitted attendances at church had not done "terribly well" but said he has seen church communities become "more engaged" with society than ever before.
"Were it not for church people, lots of organisations would not be in existence. I'm thinking of food banks and dementia groups."
His successor will be chosen in the summer.
"I take the view that once you're gone, you're gone... you've had your period in office," he added.
"I just want to leave the field clear. I don't want to make another public statement about issues again because that would be unfair on whoever succeeds me and I hope I can keep to that."
It might not seem like your idea of fun but dressing like a bat and jumping off the side of a cliff is exactly what a group of wingsuit base jumpers have been doing in China, as part of a downhill sky race.
