Aug 21 '20 at 14:28 comment added T-Pioneer Thanks @TangHo . By the way, would you like to add some new rules, such as searching on the Internet or books?
Aug 21 '20 at 14:24 comment added Tang Ho My answer for (C) is 一心一德, but 一心一意 seems correct too. (G) 君子報仇十年不晚 is correct, I would accept 未 instead of 不 too. Great job! (Wait, 德 is in the word hint)
