How much should we pay by taxi from the Warriors to the Swiss-Belhotel Liyuan?

But the hotel you mentioned is in Wuxi, which is over 1,000km from away from Xian. It is unrealistic to travel by taxi for such a long distance.

You are advised to travel by air. You may take a taxi from Terracotta Warriors Museum to Lintong Bus Station for about CNY 20. Then, take a direct bus to Xianyang Airport (about 1 hour). Or, you may take a taxi to the airport directly for about CNY 200. Afterwards, take a flight to Wuxi (about 2 hours). Upon arrival, take a taxi to the hotel for about CNY 70.

Anyway, most of the taxi drivers can only speak very simple English. They may don't understand you, but you can write Arabic numbers, so that you can communicate. ;)
