Zheng Chenggong (郑成功)

Birth Time Verification

This case uses 08:00, the Chen hour. Zheng Chenggong’s birthday is commonly recorded as the 14th day of the seventh lunar month in the Tianqi fourth year, corresponding to 27 August 1624, with Hirado, Japan as the birthplace. The key source is the Zheng family burial inscription, which says he was born in the Jia-Zi year, seventh month, fourteenth day, Chen hour. Because the day matches the historical birthday record, the hour source is treated as a literary record. With 1624-08-27 in the Chen hour, the four pillars are Jia-Zi year, Ren-Shen month, Bing-Yin day, Ren-Chen hour. Some later BaZi articles use the Wu hour, and a few materials give the thirteenth day in the Chen hour. The Wu-hour version lacks a clearer hour source, and the thirteenth-day version conflicts with the inscription. For this reading, the Chen-hour inscription is the stronger basis. The Chen hour concentrates the chart. Ren Water appears again as Seven Killings. Zi, Shen, and Chen form the Shen-Zi-Chen Water frame, so external war, regime pressure, and long-term depletion become central. Chen also stores Wu Earth Eating God, Yi Wood Direct Resource, and Gui Water Direct Officer. That means pressure turns into strategy, legitimacy, administration, and military execution. It fits Zheng’s main line: under severe pressure, he held an anti-Qing force through orthodox legitimacy, naval organization, and maritime power.

Core Analysis

Zheng Chenggong is a Bing Fire day master born in the Shen month. Metal and Water are already rising in Shen month; Ren Water Seven Killings appears on the month stem, and the Chen hour brings another Ren. The branches form the Shen-Zi-Chen Water frame. This is a chart where war, command, political change, and external pressure press directly on the self. Resource is the part that keeps the pressure usable. Jia Wood appears on the year stem, Jia is also stored in the day branch Yin, and Yi Wood is stored in Chen. Resource can carry Seven Killings, giving him legitimacy, lineage, orthodoxy, and long-range judgment. The imperial surname granted by the Longwu Emperor, and Zheng’s decision to resist Qing after his father surrendered, both sit naturally in this pressure-and-legitimacy pattern. Chen also stores Wu Earth Eating God. Here Eating God matters because it turns Seven Killings into strategy, military administration, supplies, fleets, bases, and execution. His long maritime resistance required more than courage. It required managing soldiers, ships, trade, food, and territory. The original chart also has Yin-Shen clash and punishment. Shen points to early environment and paternal power; Yin is his own stance and root. His father surrendered to the Qing while he resisted them, a clear expression of that conflict. The useful elements are Wood and Fire: Wood transforms pressure and supports the self; Fire lets Bing Fire stand. When Water becomes too heavy, victory arrives with depletion. In 1662, Ren-Yin year brought Seven Killings again and repeated the day branch Yin. His death soon after recovering Taiwan can be read through pressure converging in the year of victory.
