hi, why don`t you take a diract flight to ningbo from guangzhou,

Im not in Guangzhou, I am in Luoyang now and will take the train to Zhengshou and then fly to Hangzhou as there are not any direct flight from Zhenzhou to Ningbo. That was not my question. My question was about the best connection to take the train. Is it best from Hangzhou or from Shaoxiang

I think you could take the shuttle from Hangzhou Airport to Hangzhou Railway Station and then catch a train to Ningbo directly. Here is the Hangzhou Train Schedule(https://www.travelchinaguide.com/china-trains/hangzhou-schedule.htm) , please select one in terms of your arrival time at the airport.
