Structure:

不如 + Verb/[verb phrase]

Meaning:

When facing a choice, 不如 can also be used to mean “might as well” to emphasize the choice is the better of two options. When used like this, it is similar in meaning to 不妨.

Example:

1. 既然 已经 做了 一半 了，你 不如 坚持 下去。

jìrán yǐjīnɡ zuòle yíbàn le, nǐ bùrú jiānchí xiàqu.

You’ve already done half of it, might as well keep going.

2. 与其 空想，不如 马上 行动，做 出 点儿 成绩。

Yǔqí kōnɡxiǎnɡ, bùrú mǎshànɡ xínɡdònɡ, zuò chū diánér chénɡjì.

Rather than fantasizing, might as well take action right away. Achieve something.

As in the last example sentence, 不如 often occurs in the 与其…不如 structure, meaning “rather than X… might as well Y”.
