When communicating in Chinese you may often make mistakes using Chinese grammar like:

False:

    这里有多人。

    Zhèlǐ yǒu duō rén

True:

    这里有很多人。

    Zhèlǐ yǒu hěnduō rén

 

句中的“多”不能单独作定语，“多”的前边应当加“很”。一并作中心语“人”的定语。“很”表示程度的意义不明显。

多can not act as an attributive in isolation. It must be used in combination with 很 before it to serve as an attributive of the head word（人）. Here 很 does not hold a definite implication of a high degree.
