I NEED SCHEDULES FOR CHANGSHA BUS ROUTES # 135 AND 148. HOW LATE DO THEY RUN?

Will they be running at 10pm at night?
Does anyone know how often they run? Every hour? Every 15 minutes?
If I arrive at CS South rail station at 10:01 at night, can I take the bus and make my train at CS Station at 11:43 at night? Is it enough time?
If not,how much should a taxi be? Will it be easy to get one (at a good price)?
Thank you.
