Was the journey of Hannibal more dangerous or the long march by Mao Zedong?

From the description below,

The March of Mao Zedong was a life escape March with escape of encirclement and ambush, therefore making it the most dangerous among the two events.

Explanation:

Their commander Hannibal marched his troops, including cavalry and African war elephants, across a high pass in the Alps to strike at Rome itself from the north of the Italian peninsula. ... The Romans had presumed that the Alps created a secure natural barrier against invasion of their homeland.

For over 2,000 years, historians have argued over the route used by the Carthaginian general Hannibal to guide his army — 30,000 soldiers, 37 elephants and 15,000 horses — over the Alps and into Italy in just 16 days, conducting a military ambush against the Romans that was unprecedented in the history of warfare.

The Long March was a military retreat undertaken by the Red Army of the Communist Party of China, the forerunner of the People's Liberation Army, to evade the pursuit of the Kuomintang army. There was not one Long March, but a series of marches, as various Communist armies in the south escaped to the north and west.

it was so successful to run away from 100,000 soldiers encirclement and about 200,000 soldiers hunt between the long march. The Nationalists' thought they were successful because the communists were running away from the battle and were forced to move to the other side of China.
