1. Bus: You can take a long-distance bus from Yichang Bus Terminal or Yichang East Railway Station to Chibi or Xianning, and then get off at Jiayu County. This way is relatively cheap, but it may take a long travel time.

2. Chartered car or taxi: You can rent a chartered car or taxi in Yichang to go directly to Jiayu County, which may be more convenient than the bus, but the cost will be higher.

3. Train: You can take a train from Yichang to Xianning, and then take a bus or taxi at Xianning Railway Station to Jiayu County.

In a word, you can choose the most suitable mode of transportation according to your own needs and budget.
