What's the word to describe what you picked up when you came back from your trip?

A handwritten letter. Throughout the ages, hipsters have lived side by side for generations. During the Spring Festival, they will go home to pay New Year greetings, visit relatives and friends and say goodbye. They often bring gifts to express their deep feelings. These complimentary gifts are often called "personal letters".

The "handwritten letter" in Cantonese is a small gift that people usually give to their relatives and friends when they come back from a long trip. It is called a "personal letter" because it is not a big or expensive commodity purchased as planned, but a letter delivered by a special person.

In recent years, the meaning of handwritten letters has gradually expanded, tending to the meaning of gifts, and e-commerce stations such as handwritten letters have also been derived.

I hope my answer can help you and be adopted.
