dohodou

Could you clarify what "dohodou" refers to? The term does not point to a single widely known subject in major reference works, so providing an accurate wiki-style article requires context. For example, is dohodo u a linguistic term in a particular language, the name of a person or place, a company or project, a fictional work, or something else? If you have a link, country, or field (historical, cultural, technological, etc.), please share it. I can then draft a concise, neutral encyclopedia-style article under 300 words.
