It's just another way of saying 'They (the pleas) may come' but using a slightly more poetic contruction

'hate' is a verb which has two combinations: gerund (-ing) & the infinitive (to do). So, you can say 'I hate eating pizza' and 'I hate to eat pizza'.

'love' and 'like' also follow the same rule

Confusing, I know. We also hear people colloquially saying "I'm going to rent (out) my apartment" - meaning allow someone to use it. Same issue of a term being used in two different ways.

Hey Kai. 1. It should be "I could have done so much more TO TRY to change society" 2. Yes, "at a Chinese university" is better. 3. "occupying central" is a confusing phrases.

We can use the construction 'As well as + noun/gerund + clause' to include another thing/activity. For example, As well as shopping, I went to the bank'. Or 'As well as ice cream, I bought toilet paper'.
