To say that two things are the same, use the Mandarin Chinese yí yàng in this pattern:
Noun1 gēn / hé noun2 yí yàng.
Things can also have the same properties, indicated by a Stative Verb (SV). Use this pattern:
Noun1 gēn / hé noun2 yí yàng SV.
The Stative Verb (SV) is a verb describing a state or condition which is quite static. Examples of Stative Verbs are tall; expensive; and important.
The Nouns can also be noun-phrases such as such as “those people,” or “the tables in this room.”
Gēn / Hé
Either gēn or hé can be used as the joiner between the two nouns being compared, which in this context are translated as “and”.
Examples of Yí Yàng
This tea cup and that tea cup are the same.
Zhègè chábēi gēn nèigè chábēi yíyàng.
My father and I are equally tall. (I am as tall as my father.)
Bàba gēn wǒ yíyàng gāo.
