These disyllabic prepositions normally appear at the beginning of a sentence. Their functions are similar to those of conjunctions or to serve as transitions in communication. The following is a list of such disyllabic prepositions that are commonly used.

guān yú (關於): to bring up a new topic


guān yú wǒ mén shàng cì tǎo lùn dí nà jiàn shì , wǒ yǐ jīng zuò liǎo jué dìng le

Regarding the matter we discussed last time, I have already made a decision. 

zhì yú (至於): to bring up another topic (that already exists in context)


nǐ shuō dí nà liǎng jiàn shì , wǒ zàn chéng dì yī jiàn shì ; zhì yú dì èr jiàn , wǒ huán yào kǎo lǜ yī xià

About those two matters you mentioned, I support the first one; as to the second, I still need to think about it.

yóu yú (由於): to introduce a reason

Since 由於 is similar in meaning and usage to 因為, it can be followed by a complete sentence. In this case, it functions as a conjunction, not a preposition.

由於種種因素,原來的計畫取消了。(由於 is a preposition.)

yóu yú zhǒng zhǒng yīn sù , yuán lái dí jì huà qǔ xiāo le

Due to all kinds of factors, the plan has been cancelled.

由於老師生病了,因此我們今天沒有上課。(由於 and 因此 are conjunctive pair.)

yóu yú lǎo shī shēng bìng le , yīn cǐ wǒ mén jīn tiān méi yǒu shàng kè

Because the teacher was sick, we didn't have class today.
