Your first name of Quanh has created a practical, patient, scientific nature able to concentrate on the finer details of a project or undertaking. You are not impulsive, for you like to plan and to think ideas through before acting. You would find enjoyment and peace in an outdoor environment studying the flora and fauna of nature from a scientific point of view. A lack of fluency in your verbal expression may appear as bluntness. Your endurance and persistence enable you to carry your activities through to completion. You do not like to be interrupted or hurried once you start a project. As you keep your thoughts and feelings to yourself, this reserved quality has created misunderstandings with others because they feel left out. Sometimes moody and morbid thoughts interfere with your stability and ability to concentrate to reach your goals, especially when you are under pressure. You seldom experience the peace of mind that comes with composed thinking and emotional control. Other health problems could affect the lungs, heart, or bronchial organs.
