how much the it cost to go to zhejiang shaoxing china from B W I airport?

Do you refer to Baltimore-Washington International Thurgood Marshall Airport? If so, this city has no airport. To travel between, I suggest you take a flight to Shanghai Pudong first (Flight no. AA127 seems feasible). Then take shuttle bus line 1 to Hongqiao Train Station at the cost of CNY30. There you can take a high-speed train to your destination, which costs CNY92.5 for a second class seat and CNY150.5 for a first class seat.
