In the following sentence:
俗话说的好,要不不留学要留学就要留出个性。。。。。。这是我编的。。 我们来看看我们社会主义坚实伙伴的古巴。古巴是西班牙语国家,抽雪茄,晒太阳都是家常便饭。
What does it mean? 俗话 means "proverb" and 俗话说 means "as the saying goes", but I don't understand the 的好 part.
I feel I understand the meaning, which actually doesn't change the meaning of the 俗话说 that much I think, but I would like to grasp it more grammatically. So how does the 的好 work grammatically in this sentence?
