In the bazi classical literature 《淵海子平 yuan hai zi ping 》，there is a article titled 《身弱論 body strong weak talk》 , briefly mentioned about ways to judge the daymaster 5-element for its body strong or weak, as well as its love and hate with other 5-elements. For example,
陽木無根，生於丑月；水多轉貴，金多則折。 
Yang wood has no root when born in chou month (so weak wood). If the 4-pillars appear to have more water elements, it would turn out to be kind of noble or good fortune life (weak yang wood loves to be strengthen by the water feed). If it appears to have more metal elements, the weak wood would be broken by the strong metal (weak yang wood hates to meet strong metal).
乙木無根，生臨丑月；金多轉貴，火土則折。 
Yin yi wood has no root when born in chou month (so weak wood). If the 4-pillars appear to have more metal elements, it would turn out to be kind of noble or good fortune life (weak yi wood as yin characteristic would follow the strong metal). If it appears to have more fire and earth elements, the weak yin wood would be broken by the strong dry earth.
The above examples tell also the differences between yin wood and yang wood.
Below is the full article content which is worthy for bazi fortune reading reference.
陽木無根，生於丑月；水多轉貴，金多則折。 
乙木無根，生臨丑月；金多轉貴，火土則折。 
丙火無根，子申全見；無制無生，此身貧賤。 
六甲坐申，三重見子；運至北方，須防橫死。 
丙臨申位，陽水大忌；有制身強，旺成名利。 
己入亥月，怕逢陰木；月逢印生，自然成福。 
己日逢殺，印旺財伏；運轉東南，貴高財足。 
壬寅壬戌，陽土透露；不混官星，名崇顯祿。 
陰水無根，火鄉有貴。 陽水無根，火鄉即畏。 
丁酉陰柔，不怕多水；比肩透露，格中返忌。 
戊寅日主，何愁殺旺；露火成名，水來漂蕩。 
庚午日主，支火炎炎；見土取貴，見水為嫌。 
辛金身弱，卯提入格。 
癸酉主衰，見財成格。 
癸巳無根，火土重見；透財名彰，露根則賤。
