Matters needing attention in sending Christmas cards:

1. Choose a suitable card: choose a Christmas card that suits the occasion, style and recipient's preference. You can consider the design, color and content of the card to ensure that it meets the recipient's preferences.

2. Timing: Make sure to send greeting cards in time before Christmas, so that the recipients can receive them during Christmas. Sending it in advance can avoid missing the opportunity because of the delay in mailing.

3. Personalized content: add personal blessings and greetings to the greeting card to make it more personalized and warm. You can express your blessings, gratitude or memories to the recipient to make the greeting card more sincere and special.

4. Name and signature: Write your name and signature on the greeting card so that the recipient can know who sent the blessing. This can increase the intimacy and contact with the recipient.
