Let alone with 何况 — Chinese grammar (HSK 5)

Clause A，(更)何况 + Clause B (呢)

何况 (hékuàng) means "let alone / not to mention" and adds a second case that makes the conclusion even more obvious. The first clause often uses 都 or 也 with an easier case, then 何况 introduces the harder one. It can also add an extra reason, like "besides, ...", and 呢 at the end is common.

Examples

这个问题老师都不会，何况我们呢？ Zhè ge wèntí lǎoshī dōu bù huì, hékuàng wǒmen ne?	Even the teacher cannot solve this, let alone us.
走路去太远了，何况今天还下雨。 Zǒulù qù tài yuǎn le, hékuàng jīntiān hái xià yǔ.	It is too far to walk, and besides, it is raining today.
大人都觉得累，更何况孩子呢？ Dàren dōu juéde lèi, gèng hékuàng háizi ne?	Even adults find it tiring, let alone children.

Tip: Set up the easier case with 都 first; 何况 then points to the harder one.
