The service was great, everyone! The beds were quite nice and comfortable, and the bus company even provided passengers with bread, water, and wet wipes on board. Overall, I think Sao Nghe was the best among the three bus companies, and they arrived earlier than scheduled. The bus was clean and the lights were nice too. In general, I had a very good impression of the bus company.

The bus company's service process is very good, with very few areas needing improvement. However, it would be better if the company changed its tissue paper supplier, as the tissues have a slightly strange smell. Otherwise, I've witnessed many changes in the bus company over the past two months: drivers and bus assistants are increasingly friendly, the service process is clear and efficient, and they've resolved the transfer bottleneck in Hanoi by assigning specific zones to each bus.
