Chrysanthemum exhibition

The weather of today was very good, so my wife and I took our daughter to see the chrysanthemum exhibition in/at Shanghai university (if it's indoors then you can say 'in', but if it's outdoors then say 'at').
The fragrance from these chrysanthemums filled the air.
There were so many kinds of chrysanthemums there, and they were very beautiful.
I said to my daughter: "look how beautiful the flowers are!", but my daughter didn't care about that (care about how beautiful they were), for her, a small stone on the ground was much more attractively attractive/interesting than the chrysanthemums, OK, so I gave up!

Then we were sitting on the lawn for a rest, but my daughter didn't know what is realise that she was tired (or didn't realise that we were tired?), sometimes she ran after the other children there, sometimes she ran after the a remote control car, sometimes she ran after the a ball... so cute! (it's usually odd to use the definite article 'the' about things you haven't introduced before, unless you give more information about them)
On our way home, she finally slept sweetly in my arms. :)
