有 literally means 'to have' and is used to indicate possession, but it can also be used by extension to express 'there is/are' when followed by some undetermined object.

1. There is...at...place. → place + 有 + undetermined object

The sentence therefore needs to start with the place setting immediately followed by 有 (to have) and what occupies it.

这里有各式各样的产品。There are all kinds of products here. (lit. Here | have | all kinds of products.)

镜头上有划痕。There is a scratch on the lens. (lit. On the lens | have | scratch.)

我们去看看有没有喜欢的口味。Let's go and see if there are flavours that we like. (lit. Let's go and see | have or not | flavours that we like.) [Note that in this sentence the place is omitted.]

2. There is...at...time. → time + 有 + undetermined object

Alternatively the place setting can be replaced by the time setting.

那天有特价促销。There was a special promotion on that day. (lit. That day | have | special promotion.)

周末的时候只有我们几个游客。There were only us few tourists over the weekend. (lit. Over the weekend | only | have | us few tourists.)

今天晚上有好看的电视节目吗？Are there any good TV programmes this evening? (lit. This evening | have | good TV programmes | question marker?)
