Do I have to send flowers on Tanabata? Do we have to eat?

You don't have to send flowers, but you must prepare other gifts and have dinner together.

Because Tanabata is a traditional festival of the Chinese nation, we can express our love through festivals, prepare a favorite gift for each other, and then have a beautiful meal together, and our feelings will be stronger.

There are many choices about gifts, not necessarily flowers, but lipsticks, necklaces and so on. Life needs a sense of ritual, regardless of gender. It is not a woman's privilege to accept gifts. Both men and women should give gifts to each other. If you really can't afford a gift, you should have dinner together. If you think it's expensive outside, you can cook a big meal at home. In short, life can only be expected if it is a little different from ordinary days.
