After my family died, my colleagues followed me. How can I thank my colleagues after the funeral? How?

Although the customs of this bosom friend are different from place to place, we still have to hold a banquet to reward our colleagues. At the same time, give each colleague a gift (the deceased usually gives each person a bowl when he is over 90 years old, commonly known as the centenary bowl), and then leave a package of gifts for each person. There are towels, cigarettes and bowls inside.
