Your name of Ilwhan has formed an independent, positive, and determined personality. You are rather skeptical of new ideas that are more visionary, idealistic, or philosophical. You are more interested in being active and accomplishing the tasks you set for yourself. Your lack of expression can lead to misunderstandings and unhappiness with those close to you who do not understand your practical, candid, somewhat self-centred approach. Activities combining ingenuity and manual skills are of particular interest enabling you to excel in technical vocations, for example, as a mechanical, electrical, or electronics technician. It is what you can see, experience, and prove through compilation of facts, experiment, and logic that has greatest value to you. Once you have made a decision, you put forth great effort to accomplish your goals regardless of obstacles. Your progress is built upon your meticulous awareness of detail, your patience, and your consistent hard work. Despite your loyalty to friends, your communication at times is stilted, too candid, and frank. Health weaknesses centre in the head, resulting in such conditions as headaches, sinus problems, weak eyes, or impaired hearing.
