Many South Korean entertainment stars have taken part in a series of charity photo-shoots, posing for pictures with orphans to help them find new parents.

This year's charity exhibition, titled "letters from angels", is the fifth of its kind, having attracted many big names including actress Yoon Eunhye and actor Joo Ji Hoon.

The organizer said he hopes the activity will raise people's concern for orphans and hopes to help homeless children find normal family lives.

There are nearly 10,000 new-born babies in South Korea every year who do not live with their parents due to various reasons. With the help of others, only some 3,900 of them are adopted and find new homes.
