Baguo Portal Introduction: Baguo Gateway is the only way to the North Gate of Longtai and is the second line of defense against invading enemies. This place is condescending, with the aura that one man is in charge of everything and no one can stop him. The entire building is made of stone strips. It is not very wide but is extremely tall, extremely long, extremely dangerous, breathtaking and spectacular. It is a classic work of Chinese castle architecture. The plaque on the gatehouse reads "Xuanmao Beitang" in thick and vigorous fonts. Although it comes from the Qing Dynasty, it expresses an allusion from the Warring States Period, "The Book of Songs Wei Feng Bo Xi". This plaque is very appropriate to hang on the Ba Kingdom, because the gate of the Ba Kingdom is located just north of Longtai and is guarded by Xubian soldiers who are far away from their wives and children. This plaque can comfort people's lovesickness.
