Principle: Valentine’s Day gifts should have personalization and sentimental value.

Personalization: The gift should match the recipient's interests and preferences and demonstrate the giver's knowledge and care of the recipient. For example, if the recipient loves traveling, give them a travel journal or a travel kit.

Sentimental value: A gift should represent the emotion and meaning the giver has for the recipient. For example, you can send a greeting card made by yourself, or a souvenir that represents the relationship between the two of you.

Application: Based on the principles of personalization and emotional value, you can choose the following Valentine's Day gifts:

1. Make a personalized greeting card or photo album to show the love history of the two .

2. Give a commemorative accessory for the two of you, such as a couple bracelet or necklace.

3. Send a special experience, such as a day trip or spa experience.

4. Give a gift that represents the recipient’s preferences, such as a favorite book or a favorite set of cosmetics.

In short, Valentine’s Day gifts should be unique, meaningful, and represent the giver’s affection and care for the recipient.
