Why is 很多 sometimes before the noun and sometimes after the noun? I have sometimes seen 很多 after the noun and sometimes before and I don't understand what the reason is for it being in different places.
For instance, here it follows the noun, &quot;活动&quot;:

中国的居民社区的休闲活动很多
There are many leisure activities in the residential communities of China.

However, in another sentence I've seen, it comes before the noun, &quot;社区&quot;:

在中国，很多社区都有 老年大学 ，经常组织书法课堂活动。
In China, many communities have old people’s universities which often organize calligraphy classes.

Similarly, before the noun phrase, &quot;退休的老年&quot;:

很多退休的老年居民都参加这个活动。Many retired elderly residents participate in this activity.

What is the reason for these various locations of 很多?
社区的休闲活动很多 is a [topic]+[comment] sentence


[社区的休闲活动] is the [topic]


[很多] is the [comment]


[社区的休闲活动][很多] = Community recreational activities are plenty

&quot;很多社区的休闲活动&quot; = &quot;Many community recreational activities&quot; (it is an incomplete sentence)

政府資助很多社区的休闲活动 = The government subsidizes recreational activities in many communities


It is a [svo] sentence. The adjective '很多' (many) is directly placed before the noun phrase 区的休闲活动 to modify it.

More example:
公園(是)很大的 = Parks are big - [Topic: 公園 + comment: (是)很大的]
很大的公園 = A big park [SVO]
公園很大 = (this) park is big - [Topic: (this) 公園 + comment: 很大]
