Expressing "even if…" with "jiusuan"

就算 (jiùsuàn) is an informal way of saying "even if", However, unlike 即使, 哪怕 and 就是, 就算 has a feeling that the speaker doesn't believe that the hypothetical statement is reasonable or has any chance of being realized.

就算 + hypothetical statement + 也 + action.

For example:

• 她 就算 是 白羊座 的，那 又 有 什么 影响？
• 就算 你 说 对，又 有 什么 关系？
• 就算 你 不 能 准时 到 也 不 要紧，我们 等 着。
• 就算 你 有 了 权力，也 不 能 违背 你 的 原则。

又 is often used in the last statement to further emphasize the lack of importance of the first statement.

Note that the clause used after 就算 must be hypothetical, otherwise 虽然 should be used.

For example:

• 现在 虽然 是 高峰期，但 无论如何 都 要 出去，太 饿 了!
• 就算 现在 是 高峰期，也要 出去，太 饿 了!

In the sentence above, it being rush hour is not a hypothetical statement, so it is incorrect to use 就算.
