Getting to the Tulou houses in Longyan

Hello,

I have several questions regarding how to get to the Tulou houses. We live in Fuzhou and have seen that you must first take a train to Longyan city and then take a taxi to the Longyan bus station, and finally a 2 hour bus ride to the Hakka houses. Altogether about a 5.5 hour trip from FZ.

I also saw that if we travel to the Earth Towers from Xiamen, there is a bus that directly goes there and only takes 3.5 hours from the South Hubin bus station in Xiamen.

If that is the case, can you please tell us the first bus departing from the Xiamen South Hubin bus station to the scenic area? Also, what is the latest bus back to Xiamen? Is "Tulou house" the name of the bus station in Longyan? Please let us know, we really appreciate your help.
