The process of making Dragon Boat Festival greeting cards is as follows:

1. Make rice dumpling leaves. Cut out a larger round piece of white paper, then cut out a smaller rice dumpling leaf, and draw the veins with a blue pen (as shown in the picture).

2. Attach the rice dumpling leaves. Follow the previous step, cut out another rice dumpling leaf, and then cross-post the two rice dumpling leaves on the round paper (as shown in the picture).

3. Make rice dumplings. Use white paper to cut out the shape of a rice dumpling, draw an expression, then wrap it with the prepared rice dumpling leaves and fix it with glue (as shown in the picture).

4. Paste the rice dumplings. Follow the third step to make a second rice dumpling, and then attach the two rice dumplings to the original rice dumpling leaves (as shown in the picture).

5. Paste the word "Dragon Boat Festival". Finally, cut out the word "Dragon Boat Festival" and paste it directly above the two rice dumplings, and then draw heat on the rice dumplings. Simple Dragon Boat Festival greeting cards are handmade.

The impact of the Dragon Boat Festival on foreign countries:

Japan has had the tradition of celebrating Chinese festivals since ancient times. In Japan, the custom of Dragon Boat Festival was introduced to Japan from China after the Heian period. Starting from the Meiji Era, various holidays have been changed to Gregorian calendar days. The Dragon Boat Festival in Japan is May 5th in the Gregorian calendar. After the customs of the Dragon Boat Festival were introduced to Japan, they were absorbed and transformed into Japanese traditional culture.

The Japanese do not row dragon boats on this day, but like the Chinese, they eat rice dumplings and hang calamus grass in front of their doors. In 1948, the Dragon Boat Festival was officially designated as a statutory Children's Day by the Japanese government and became one of the five major festivals in Japan.
