For a person who ever did labor work, it is not hard to finish a100 kilogram burden. Simply run two trips and you can easily finish it.
Only a stupid person tries 100 kilograms in one trip. My dad always told me: if you can do 40, do 30 and never try 50. Plus, never compete/confront people who claims he can carry heavy danzi (burden).
Be smart, not be stupid!
