How to get there ?
==============
1. Take a Tiger Airways flight to Hanoi. Take a cab to the bus station & ask for a bus to Ping Xiang.
2. The bus will take you to border. Chop viet side. A buggy will take tourists in batches to China side. Chop passport again. A mini van will then take you to PingXiang. All the while your bus company will give you a purple sling tag. Just wear it all the time so they can find you.
3.Take a RMB 30 taxi or RMB 2 public bus from PingXiang to Puzai.
4. Check in to a hotel by walking in. Always have rooms. Tien Bao is the one I chose. It was very clean, nice & and spacious for overnight bonks.
5. Hanoi to PingXiang bus journey will take around 3 hours. From landing in Hanoi to reaching Puzai the whole thing will take about 5 to 6 hours depending on how fast you get connecting bus etc.
Second Way
=========
1. Take a Jetstar flight to Nanning.
2. From Nanning's bus station take a luxury double decker coach (costs RMB 68) to PingXiang.
3. After the 3.5 hours journey, take a bus/taxi to Puzai another 20 min journey.
Hope this answers all the "exact location" and "How to get there?" questions.
