There are two flights from Zhengzhou to Nanning. After getting off the plane, Nanning took a taxi to Langdong Bus Station, which was about the taxi fare in 70 yuan. Then you can take the express train from Nanning to Hechi, and the fare is about 1 10. The express from Nanning to Hechi is Babido, which is available at all bus stations. The journey time is about 3.5 hours, and there should be a bus every hour.
There are also flights to Guilin, and there is an express bus from Guilin bus station to Hechi, which takes about four and a half hours, but the number of trains is not as much as that from Nanning to Hechi.
The airport in Hechi has not been built yet.
If the airport is repaired, you can go directly from Zhengzhou Xinzheng Airport to Hechi. There are many pyramid schemes in Guangxi. Don't be cheated.
