I need help translating and orienting two signature chops (Characters identified: 精忠報國 忠誠衛士)
The first one (精忠報國 or 精忠报国 in simplified characters) means to serve one's country with absolute loyalty and make all sacrifices. There is a story tied to this phrase. In the Song Dynasty (around early 1100s CE), there was a famous general called Yue Fei. In order to remind him to serve his country and encourage him to fight against the nomadic invaders, his mother tattooed these four characters on his back.
The second one （忠誠衛士 or 忠诚卫士 in simplified characters) means a loyal defender. There is no story behind this phrase, but it is commonly associated with the Chinese armed police forces.
These two phrases have little to do with your names unless you are part of the military or police.
