Your first name of Yanglei gives you self-assurance, independence, and confidence. Having the confidence and will power to follow through on your objectives does not give you a lot of understanding for those who are lacking in initiative. You work best as your own boss as you are self-motivated and decisive, and resentful of someone telling you what to do. You have depth of mind and the ability to concentrate and to follow a line of thought to a logical conclusion. As you are not demonstrative of your feelings, others know they can lean on you for support and protection. Your love of challenging the concepts of others invariably leads you to create your own ideas and to pioneer new lines of thought. You must be independent and you do not brook interference in any way. Although you are good natured and never intend offence, nevertheless your strong mindedness and candid manner of expression could put a strain on close relationships. Problems with your health centre in the head and could cause you to suffer either with head tension, head colds, headaches, or sinus congestion. You have to be your own boss as it is most difficult for you to submit to direction from others.
