Foreigners often make some strange mistakes in Chinese when they study the most difficult language— —Chinese. We try to analyze typical sentences to correct these errors.
Yǒu yì zhī niǎo diào jìn gāng.
False: 有一只鸟掉进缸。
Yǒu yì zhī niǎo diào jìn gāng lǐ.
True: 有一只鸟掉进缸里。
“缸”是个表示实体的名词，不能单独用来作“掉进”的宾语。须在“缸”后加上方位词“里”，表示处所。
As a noun denoting entity, 缸 can not be the object of 掉进 just by itself， but ought to be followed by the noun of locality 里， to show location.
