I found n like to recommend this short free-distribution 14 pages book in Pork Kark See to be quite good for young children to read to inculcate in them good moral virtues such as filial piety, gratitude and compassion from when they are young.
Parents could teach their children to have good moral values from young by familiarising them with these simple n easy to understand stories
Book title: 'We are good children'
