How to take a bus from Henglong Business Building, Wenzhou Station Avenue to 18 Rui 'an?

There seems to be something wrong with getting off work at 6: 30 in the evening and taking the bus:

Bus route: 17 → 19, the whole journey is about 37.8 kilometers.

1. Walk about 250 meters from Henglong Business Building and arrive at Xialupu (Huaxia Bank) Station.

2. Take bus 17 (the last bus is 19: 00), pass 7 stops and arrive at the bus stop.

3. Take bus 19 (the last bus is 18: 00), pass 33 stops and arrive at 18 stop.
