One quick note to share and this will definitely scale up QiMen analysis.
This idea is adopted from DLR (大六壬) and had used it for a while+ felt it quite grounded.
Basically, when we look at the 8 Deity (or 9 Deity), namely 值符，腾蛇，太阴，六合，白虎，玄武，九地，九天 + 太常，朱雀，勾陈; we should identify if these deity element nature and whether they are in season or off season. When a deity nature is negatives but meet with produce in season, the inauspicious aspect of that deity is negated. But when the season is clashing the deity or producing out, the inauspicious aspect is promoted or activated.
