1. For zwds, we called the first year of the decade as the “entering year” and the last year of the decade as the “exiting year”.
2. Regardless the year/month luck in here, if your decade palace was impacted by any kind of Si-Hua, for example, Decade Self Shines the Life Self or Decade Self clashed the Life Self etc, then the first/last year will be the most impacted year in general. In other words, if Si-Hua impact is good, then the first and last year would be better; if Si-Hua impact is bad, then the first and last year would be worse.
3. In the last year of the decade:
1) If my general luck of this decade is worse than next decade because of the Si-Hua impact, then I will have a big celebration at the end of this year (in Chinese calendar) — to make a clear change from my mind and make myself ready to the new decade.
2) If my general luck of this decade is better than next decade, then I will try to extend my good luck as long as possible, make less change in mind and in reality.
4. We also can get into the Year/month level to find the good/bad, lucky/unlucky …etc, for any year and any month.
