 I love teaching when students love learning :)

These photos are real, no posing.

Some little lighting lightens the room

I've added a table light to my room. Now it's warm and nice :)

And since we must Instagram every photo nowadays so I make some random effect on the photo as well.

*p/s: if you think this photo quite dark and underexposed, it's your eyes problem, go find doctor check check. Another possibility is your computer screen is very very dusty, yeah, just wipe and you see this photo bright like sunlight.
