Charity in China is deeply rooted in the guanxi tradition and mainly involves strong ties. In the wake of emerging social media, online charity (also known as micro-charity) has become increasingly popular over the past few years.

Their charitable behaviours are steered towards connecting, communicating, and eventually contributing to the formation of a powerful digital environment, which essentially diffuses the awareness of responsibility and commitment.
