This workshop brings together the teams and collaborators of the Sino-German collaboration on the  "Systematic study of stellar populations in star clusters" (DFG/NSFC, Dali Univ. Zhongmu Li/Heidelberg Univ. Rainer Spurzem), the Sino-Austrian collaboration (U Vienna, G. Hensler/R. Spurzem), the China-Kazakhstan collaboration (Fesenkov Astrophysical Institute Almaty, C. Omarov/R. Spurzem), and the teams of Silk Road Project (XJTLU Suzhou, T. Kouwenhoven/Beijing/...) and Dali University.  With the help of dynamical simulations of star clusters, advanced stellar population synthesis and dynamical studies of star clusters are combined; models of star clusters with binaries and planetary systems are presented; dynamics of galaxies and galactic nuclei, with gas, stars, and black holes. We focus also on investigation of star clusters with both photometry and spectroscopy methods, used equally for observational and simulation data.

The high-speed train from Kunming to Dali and returns

The high-speed train from Kunming to Dali and returns are very frequent (around every half hour from 7:40 am to 9:00 pm) and convenient (about 2 hours trip). Please note there are three strain stations in Kunming, all the trains from Kunming to Dali depart from the Kunming station. You can check the train schedule from the website here.

Intra-city traffic

The workshop will held in the Landscape Hotel (Chinese name: Lanlinge Hotel) . Landscape Hotel is located at No. 96 Yuer Road, the ancient city of Dali, which is adjacent to Erhai Lake in the East and Cangshan Mountain in the west. It is the only hotel in the ancient city of Dali to display the different patterns of Bai architecture in Bai courtyard style.

 

The map around landscape Hotel, restaurants and other useful spots are marked on the map

 

You can get to the hotel by city transportation or taxi from the airport or railway station. We list the Intra-city traffic information, please check it.

 

 

About Dali

Dali Bai Autonomous Prefecture is located in the west-central part of Yunnan Province, with an elevation of 2090 meters, is a city with natural scenery, national characteristics and historical background. Dali has spectacular views of the surrounding countryside. Nearby are the ancient city of Dali and the spectacular Chongsheng Buddhist Temple with its three miraculous pagoda towers. One hundred miles to the north is another beautiful ancient city, Lijiang, a UNESCO Heritage Site, framed by the 18,000 foot Jade Dragon Snow Mountain, and roughly thirty miles away from that is the Lijiang Station of the Yunnan Astronomical Observatory with its 2.4-meter telescope.

Dali has beautiful mountains and rivers, the most beautiful and clear lake in the whole southwestern region-Erhai Lake, and the beautiful and magnificent scenery of Cangshan and Laojunshan.

 

The view of Cangshan and Erhai

 

Dali Ancient City has been built for more than 1200 years, with Erhai Lake in the East and Cangshan Mountain in the west, forming a chessboard pattern of "one water around Cangshan, Cangshan embracing the ancient city". The cultural atmosphere here is rich, and friends from all over the world gather. It is an excellent place for sightseeing, vacation and literary and artistic exchanges.

 

The view of Dali Ancient City

 

The Three Pagodas of Chongsheng Temple is a national 5A scenic spot. Chongsheng Temple is currently the largest single monastery of Han Dynasty in China. From 937 to 1253, among the 22 kings of Dali Dynasty, there were nine Kings who were Zen monasteries and then monks. Therefore, Chongsheng Temple enjoys the reputation of "Royal Monastery" and "Buddhist Capital".
