Expressing “From beginning to end” with “cóngtóu dào wěi”

这部纪录片我从头到尾看了两遍，越看越觉得其中很多细节值得深思。

Zhè bù jìlùpiàn wǒ cóngtóu dào wěi kàn le liǎng biàn, yuè kàn yuè juéde qízhōng hěn duō xìjié zhídé shēnsī.

I watched this documentary twice from beginning to end, and the more I watched it, the more I felt that many details in it were worth deep reflection.

他把整个过程从头到尾讲得非常清楚，连最容易被忽略的环节也没有漏掉。

Tā bǎ zhěng ge guòchéng cóngtóu dào wěi jiǎng de fēicháng qīngchu, lián zuì róngyì bèi hūlüè de huánjié yě méiyǒu lòu diào.

He explained the entire process from beginning to end very clearly, without missing even the steps most easily overlooked.

这场争论表面上只是意见分歧，实际上从头到尾都涉及更深层的信任问题。

Zhè chǎng zhēnglùn biǎomiàn shàng zhǐshì yìjiàn fēnqí, shíjì shàng cóngtóu dào wěi dōu shèjí gèng shēn céng de xìnrèn wèntí.

On the surface this argument was only a disagreement in opinion, but in fact from beginning to end it involved a deeper issue of trust.
