9 Star Ki was popular in London in the early years of feng shui’s growth in the UK. It is a Japanese simplified version of the Ba Zhai or Eight House system calculation of a person’s ‘gua number.’ However it calculates female Ki numbers the same as male numbers, which is not the case with the original Ba Zhai calculation. It is principally used to characterise individuals by a three-number “code,” one number relating to each of the year, month and day of birth. Experts can use it to derive forecasts, both personal and more general.
