For now, I am still tweaking. Opinion/suggestion from Lu Sheng by Mr Michael that there will be no end to tweaking, that's true but for a perfectionist like myself, I wanted to show the best, but come to think of it, there will be subjective views and " What is the best??? "
Despite those, I carry on tweaking. However, there was still some particles stuck at the emitter. To fix this, a fan node was place in position slightly behind the emitter to blow out all the stuck-particle. To get the position of that specific place, a vopsop to normalize the normals and a polyextrude to get the position.
polyextrude for the fan position
expression to use the position to put fan
