Towel: In ancient times, people who lost their families accepted the shoulders of relatives and friends, and gifts needed to be returned, which was called "return paper".
On the 30th, 50th, seventieth and hundredth day, or on New Year's Eve, give back "cakes", "steamed stuffed buns" and "face turtles" to relatives and friends to show their gratitude.
Now they still use daily necessities, and towels and soap are the most common ones. It is customary to send hangers, towels and handkerchiefs at funerals now, which is a custom left over by the Japanese during the Japanese occupation.
Answering paper with a towel began in the Japanese occupation era, and recently it was answered with a towel while receiving gifts.
