The travel superlatives list just keeps growing in China, which just marked 100 years of the Chinese Communist Party.
In Shanghai, travellers can check into the world's tallest hotel: J Hotel Shanghai Tower.
Perched on the top floors of the 632m Shanghai Tower — China's tallest building — the hotel opened on 19 June with 165 rooms, including 34 suites.
Rooms and suites, located from levels 86 to 98, vary from 62sqm to 380sqm.
The hotel also features 24/7 butler service, Chinese tea sets in every room, toiletries by Hermes and Diptyque, an indoor swimming pool, health management services and an anti-ageing spa.

Another mega-airport opens in China
In Sichuan, the Chengdu Tianfu International Airport waved off its inaugural flight by Sichuan Airlines on 27 June, bound for Beijing.
Chengdu, the capital of Sichuan province, is China's third city to have two international airports — after Shanghai and Beijing.
The new Tianfu airport is currently restricted to domestic flights, with only two terminals and three runways are in operation.
But when the RMB70 billion Chinese (US$10.8 billion) airport fully opens up, its annual handling capacity will shoot up to 120 million passengers, reported state media outlet Xinhua.
Chengdu Tianfu International Airport will feature new technologies such as self check-in kiosks, self-boarding gates, facial recognition software and AI robot concierges.
A new metro line connecting the new air hub to Chengdu Shuangliu International Airport is expected to be launch in 2023.

A high-speed train to the "roof of the world"
In China's vast interior, Tibet's first bullet train has entered into service on 25 June, linking Tibetan capital Lhasa with the city of Nyingchi.
Taking six years to construct, the US$5.6 billion project is run by state-owned China State Railway Group.
The 435km Lhasa-Nyingchi lineline passes through a total of 47 tunnels and 121 bridges, including the 525m-long Zangmu Railway Bridge, the world's largest and highest arch bridge.
To manage the high altitudes, cabins are pumped with constant oxygen levels at 23.6% — higher than the usual 21% in normal circumstances — and special glass windows to handle Tibet's high UV levels.
However, the trains in Tibet operate at about 160km per hour, significantly slower than the maximum speeds of 350km per hour on many of China's other lines.
