The point that is considered the starting point of the fall of Tang Dynasty is during Emperor Mu Zong reign, around the year of 821-824. He is known for his high-spending, alcoholics habits and as neglectful emperor.
The correct answer is The fall of the Tang Dynasty began with lack of leadership.
Explanation: As is often the case, the fall of the Tang Dynasty began with the rise of corruption from within. Emperor Xuanzong (712–755) severely neglected his duties; as a result, corrupt officials often ruled in his place. This eventually caused unrest among the population, and rebellions erupted. A series of uprisings followed, one after another, each weakening the empire.
