# Description:
# Galih and Ratna married during the COVID19 period
# and only invited the families of both parters.
# They rented a number of minibus to pick up all of
# their families to go to wedding. But during the COVID19,
# the government held a PSBB program to reduce the impact
# of the spread of the virus. Each minibus only can carry
# at most 4 passengers.
