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”.
