Key to a happy HK family could be a mobile messaging group on WhatsApp or WeChat

Encouraging families to use technology wisely to improve their relationships is one aim of the Smart Family-Link Project.

Families who communicate through group messaging on mobile platforms such as WhatsApp and WeChat are happier, according to a survey by the University of Hong Kong.

The study by the School of Public Health found 72% of local families were keeping in touch via online groups, and the frequency of communication also affected happiness.
