Clapping hand

During the time when my parent to taiwan, i was very boring. Only wai po, wai gong and me at home. So boring......
I always made noise in the spring cot because i wanted them to hug me walk around. I was so angry and hit my palms together....
I was very confusing... Why wai po laughed and praised me as a good girl seem i was wrathful??
Oh i see, this is called clapping hand. So i clapped my hand all the time.. hehehe..
