if you want the style of the engagement party to be traditional and cultural, then using traditional Chinese characters may be more in line with this style. Traditional Chinese characters have a long history and cultural background, which can add some classical charm to the engagement party.
however, if you prefer a concise and modern style, it may be more appropriate to use simplified Chinese characters. The strokes of simplified Chinese characters are simple and clear, and the visual effect is more concise and clear, which can make the whole engagement party more fashionable and modern.
In short, the choice of traditional Chinese characters or simplified Chinese characters depends on your personal preference and the overall style of the engagement party, which can be weighed according to the actual situation.
