Highly recommend you to take the bullet train departing from Beijing South Railway Station to Tianjin. The trains leave for Tianjin frequently every day and just take about 30 mimutes on the way, The fare is about 60RMB per person.

Both ok! You can take inter-city bullet train at Beijing South Railway Station to Tianjin. It is faster, but the ticket is a bit higher: 58rmb for half a hour. The train departs every 15 minutes. So, few people choose to go by bus. If you want to travel by bus, you should get to Zhaogongkou Bus Station, which is not far away from Beijing SOuth Railway Station. It takes about 1.5 hours.
