多年以后，他才愿意提起那些痛苦的往事。

Duōnián yǐhòu, tā cái yuànyì tíqǐ nàxiē tòngkǔ de wǎngshì.

Many years later, he was finally willing to bring up those painful past events.

有些往事不必忘记，但可以学着放下。

Yǒuxiē wǎngshì búbì wàngjì, dàn kěyǐ xuézhe fàngxià.

Some past events don't need to be forgotten, but we can learn to let them go.

听着这首老歌，很多往事一下子涌上心头。

Tīngzhe zhè shǒu lǎogē, hěn duō wǎngshì yíxiàzi yǒngshàng xīntóu.

Listening to this old song, many past events suddenly came to my mind.
