As far as I know, among the three universities, Zhonggong and Tuhua are famous, and they have training in every province and city in the form of national examination. If you take the national examination, you can choose them; Beiyang Yanyuan is not as famous as Zhonggong's painting, but it is specialized in Tianjin. As far as I know, it performs best in Tianjin. In Selected Graduates, civil servants and professional editors are very professional. If you take an examination of civil servants in Tianjin, I suggest you choose Beiyang Yanyuan!

Wish you success! !
