When giving a lecture, Kinga charged 30 mon (unit of copper currency) per person (auditor), and as it is said that more than 150 persons per day listened to his lecture, accordingly Kinga earned about 4 kan 500 mon (the term kan is a unit of copper currency in Edo, the 4 kan equaling 4,000 mon equaling 1 ryo [unit of gold currency]) per day, which was sufficient for clothing, food and housing expenses.
この際一人当たり30文を講義料として徴収しており、日に150人以上集ったということであるから銅銭4貫500文を得ていたことになり衣食住には充分な稼ぎだったようだ。
