I am kinda new to the game! I need some explanation between the synergy of 2 cards and in general, the order of resolving creature abilities with multiple effects at once.

effect A) wan entered therefore i sent a target nonland permanent from the field to the owner's library
effect B) because A was triggered, i get 2 spirit tokens.

Lets assume wan shi tong is played when katara is already in the field. what is the process of events?

1. effect A triggers twice, therefore we have A1 and A2.
   now, the order of events is: A1 is being resolved, triggering B. then A2 is being resolved, triggering B again.
   leaving me with 4 tokens.

or

2. effect A triggers twice, therefore we have A1 and A2.
   now, the order of event is: A1 triggers. then A2 triggers. now because 1 or more cards were put into a library, effect B triggers, leaving me with 2 tokens.
