Qi Men Dun Jia (QMDJ) is an ancient form of divination. It is one of the Three Methods (三式) of Chinese Divination, with Da Liu Ren and Tai Yi Shen Shu. Although it started out from China, it now widely practice in the East as well as in the West.
To get to the point (cutting the long story short), besides using QiMen to locate and connect with one’s Guardian / Deity; QiMen can be use to locate and activate one Personal Wealth Sector.
While the Guardian / Deity can help one’s to manifest certain outcome or desire, the Personal Wealth Sector could help one achieve that 1 needed breakthrough in wealth and set the pace forward. This Personal Wealth Sector is the “Life Door” or 生门 in one’s personal QiMen chart. To identify this in the chart, one’s need to use his or her own date of birth + time to plot it out (there are many QMDJ app and free calculator available online).
Just to value add, beside using “Life Door” or 生门 for wealth, one can also use “Open Door” or 开门 for opportunities and “Six Harmony” or 六合 to activate marriage bliss and household harmony.
