Identify ~6-7mm long green creature
Let's take a look at the magnified body of the insect (it is a nymphe btw) - we can see 2 brown dots one above the other along the body line. This pattern is very suggestive to Chelinidea species (the most common is Chelinidea vittiger aequoris):



I stop my search at Coreidae family, because multiple species (a lot of bugs actually) of this family have similar appearance, for example:

Gonocerus acuteangulatus:



But other enthusiasts can start from here (Coreidae family) and trace it down more precisely - I am sure they will succeed.
