Fixed Multi-Part Constructions: 一方面...一方面, 之所以...是因为, 不仅...还

By the advanced level, you've met plenty of paired connectives: 因为...所以, 虽然...但是, 如果...就, and so on. This article covers three more that belong to the same family but sit a bit higher in register and show up more in structured writing and prepared speech than in everyday chat. Getting comfortable with them makes a real difference to the quality of formal written Chinese.

一方面...一方面: "on one hand... on the other hand"

一方面...一方面 (yī fāngmiàn...yī fāngmiàn) lays out two aspects of the same situation side by side. It's the equivalent of "on one hand... on the other hand" in English, though it doesn't have to imply tension or contradiction. Often it's just pointing to two things that are both true at the same time.

一方面 + [First Aspect], 一方面 + [Second Aspect]

• 这份工作一方面薪水不错，一方面离家很近，所以她很满意。(Zhè fèn gōngzuò yī fāngmiàn xīnshuǐ bùcuò, yī fāngmiàn lí jiā hěn jìn, suǒyǐ tā hěn mǎnyì.) -- This job pays well on one hand, and on the other it's close to home, so she's very happy with it.
• 一方面需要提高效率，一方面也要保证质量，这两者并不矛盾。(Yī fāngmiàn xūyào tígāo xiàolǜ, yī fāngmiàn yě yào bǎozhèng zhìliàng, zhè liǎng zhě bìng bù máodùn.) -- On one hand we need to improve efficiency, and on the other we need to ensure quality. The two aren't contradictory.

The second 一方面 is often replaced by 另一方面 (lìng yī fāngmiàn, "on the other hand") to make the two-sidedness more explicit:

• 政府一方面加大了基础设施投入，另一方面也推进了相关制度改革。-- The government on one hand increased investment in infrastructure, and on the other pushed forward institutional reform.

If you've got three points to make, 一方面...另一方面... can start to feel a bit clunky. For three or more points it's usually cleaner to switch to 首先...其次...最后 (firstly... secondly... finally).

之所以...是因为: "the reason why... is because"

之所以...是因为 (zhī suǒyǐ...shì yīnwèi) is the formal written way of explaining why something happened. In spoken Chinese you'd just say 因为...所以. What makes this construction different is the order: it starts with the result and saves the reason for the end, which puts more weight on the explanation.

之所以 + [Result], 是因为 + [Reason]

• 这项政策之所以受到广泛支持，是因为它切实解决了民众的实际问题。(Zhè xiàng zhèngcè zhī suǒyǐ shòudào guǎngfàn zhīchí, shì yīnwèi tā qièshí jiějué le mínzhòng de shíjì wèntí.) -- The reason this policy's gotten such wide support is that it genuinely addresses people's real concerns.
• 他之所以能够成功，是因为他始终保持着对目标的专注。(Tā zhī suǒyǐ nénggòu chénggōng, shì yīnwèi tā shǐzhōng bǎochí zhe duì mùbiāo de zhuānzhù.) -- The reason he was able to succeed is that he kept his focus on his goal the whole time.
• 之所以做出这个决定，是因为我们综合考量了各方面的因素。-- The reason we made this decision is that we weighed up factors from all sides.

It's worth comparing this directly to the spoken version:

• 口语: 因为他太努力了，所以他成功了。-- He succeeded because he worked so hard.
• 书面语: 他之所以成功，是因为他付出了常人难以想象的努力。-- The reason he succeeded is that he put in effort most people can't imagine.

The written version starts with the result, holds the explanation till the end, and gives it more weight. The construction does some of that work for you automatically.

In spoken Chinese, 之所以...是因为 doesn't sound wrong, but it does sound deliberate and a bit formal. It's best saved for writing and prepared speech.

不仅...还: "not only... but also"

不仅...还 (bùjǐn...hái) is a close cousin of 不但...而且 from an earlier article. Both mean "not only... but also," and in a lot of sentences they're interchangeable. There are a few practical differences worth knowing.

不仅 + [First Point], 还/也/而且 + [Second Point]

• 这本书不仅内容丰富，还文笔优美。(Zhè běn shū bùjǐn nèiróng fēngfù, hái wénbǐ yōuměi.) -- This book isn't only rich in content, it's also beautifully written.
• 他不仅会说中文，还会说日语和西班牙语。(Tā bùjǐn huì shuō Zhōngwén, hái huì shuō Rìyǔ hé Xībānyáyǔ.) -- He can speak not only Chinese but also Japanese and Spanish.
• 这次改革不仅降低了成本，还提高了整体效率，同时也增强了团队凝聚力。-- This reform didn't just reduce costs, it also improved overall efficiency and strengthened the team.

不仅 versus 不但:

Both work in spoken and written Chinese, but 不仅 leans a bit more formal and shows up more in writing and prepared speech. 不但 is perfectly natural in conversation. In a formal essay or report, 不仅 is usually the better fit.

还 versus 而且 after 不仅:

还 after 不仅 feels lighter and works in both registers. 而且 is a bit more emphatic, signaling that the second point is significant or surprising. If the second point is the real news, 而且 fits better.

• 这个方案不仅可行，而且比现有方案成本低三成。-- This plan isn't just workable; it's actually thirty percent cheaper than what we have now. (而且 signals that the cost point is the main news.)
• 她不仅聪明，还很努力。-- She's not only smart but also hardworking. (还 adds the second point more evenly.)

不仅如此 (bùjǐn rúcǐ, "not only that") is a handy fixed phrase for adding a further point beyond what was just said. It often opens a new sentence:

• 这项技术已经在多个领域得到应用。不仅如此，研究团队还在开发下一代系统。-- This technology's already being used in multiple fields. Not only that, but the research team is also developing a next-generation system.

Using all three in formal writing

These three constructions work well together in analytical writing: 之所以...是因为 to open an explanation, 一方面...另一方面 to lay out two parallel factors, and 不仅如此 to push into a third point. Getting fluent with them is a practical step toward writing Chinese that feels structured and considered rather than just grammatically correct.
