He reigned from 1127 until 1130 when he died at age 33 after being deposed by Empress Dowager Cixi who took control of state affairs following her husband’s death due to illness or poisoning rumors spread about him leading up later historians questioning legitimacy as well credibility within historical records regarding this event occurring under his rule without any major accomplishments recorded outside those related solely towards family matters like marriages involving royalty members etcetera so there isn't much more information available on him since it seems mostly overshadowed by other notable figures during same time frame especially compared against earlier mentioned rulers' achievements listed above respectively here we see how different each person can be even though they share similar roles yet their impact varies greatly depending on personal abilities strengths weaknesses along with societal factors influencing outcomes achieved while holding office position held - all these factors combined make understanding complex human behavior difficult task indeed!
