We took the bus from Urumqi 乌鲁木齐 to Turpan 吐鲁番. In Turpan, we hired a taxi for 600 RBM (about S$120) to show us the places of interest. We visited the Thousand Buddha Caves 千佛洞, Ancient City of Jiaohe 交河故城, Museum of Turpan Karez Paradise 坎儿井民俗园, the Sugong Pagoda 蘇公塔 and the Prince Jun Palace 郡王府.
The trip includes lunch but we have to pay for the entrance fees. Though the driver was very friendly and recommended, I think this is very expensive unless you have 4 people to share the taxi cost.
Maybe should we take the group tour for 150 RMB (S$30) per person. 
There is an underground tunnel in Prince Jun Palace. Maybe this is the escape route as there were many fights during that time. An interesting place to visit for S$4.20 entrance fee. Can forget visiting the Sugong Pagoda. Not worth paying S$9.40 to get into it.
