Comparing “qíshí” and “shíjì shàng”
其实 vs 实际上
How it works
Both 其实 (qíshí) and 实际上 (shíjì shàng) can mean “actually” or “in fact.” Both are used to reveal the real situation behind appearances or assumptions.
However:
其实 (qíshí) is more common in spoken language and everyday explanation.
实际上 (shíjì shàng) is more formal and more common in analytical or written contexts.
