What are these asterisks? like the **ell of daisy dilutes the grey **oking?

Hard to tell. Whoever wrote that is certainly not a native speaker and their intent is hard to discern through their haphazard version of English. And there isn't any particular reason in English for asterisks there. I''d say the most common usage for asterisks in similar circumstances is to censor swear words, but there isn't one I'm aware of that would be **ell (some particularly fundamentalist Christians may censor "hell", but that wouldn't be two asterisks and makes no sense in the context). That might be "smell of daisies", i.e. something pleasant as an anodyne for negativity and depression of "the grey **oking"--maybe "choking"?
,

I wonder if it is a machine translation that failed to process some words. It is very clumsy, and not native English. There is no way to tell what the asterisks mean. Possibly "smell" and "choking". Native speakers might prefer "scent" to "smell" when referring to flowers.

Yeah, poor machine translation seemed like a possibility to me too.

I think this is the original

It is some Chinese person's amateur effort. Maybe the asterisks are a typing error that would pass unnoticed by non-Occidentals?

I'm curious what you make of the entire piece - the context you've offered makes as little sense as the asterisks do.

Oh my.

That is dreadful.

Better than my Chinese will ever be, but still dreadful.

<sigh> what sentiment. a blocked gizzard must be so painful

If I were "in a girl's face" I should expect her to have the blocked gizzard.

Well, guys. At least the writer has written a correct sentence:
Love when you are ready, not when you are lonely.
