眼泪是忠诚眼泪是盐水
[yăn lèi shì zhōng chéng yăn lèi shì yán shuĭ]
This means 'Tears are faithful, tears are saline.' Tears can be seen as a reflection of sincere emotions such as sadness, joy or loyalty while physiologically they are just salty water. Tears are the body's way of expressing the depths of emotion that words sometimes fail to do.
