I want to know the answer to the following question:
What is a commonly seen example?
All the background I'm provided with is that "A commonly seen example is the double happiness symbol 囍, formed as a ligature of 喜喜 and referred to by its disyllabic name (simplified Chinese: 双喜; traditional Chinese: 雙喜; pinyin: shuāngxǐ).". Is that enough to answer the question?
