“Knowing people and knowing ourselves. We will win a hundred battles without losing.” ‘Knowing people’ means insight into target groups, and reaching consumers at the right time and place is the most important aspect of brands or products as well as sale volume.

It means the understanding of brands or products from their perspective, and also from target groups’ perspectives, in order to ensure effective online marketing.
