If that is the case, why do have to say "Chinese side, the number of Chinese soldiers who sacrificed their lives during the conflict was far less than the number of India's."Says who? The US media? The one that reported 40+ Chinese dead the day after and then the Indian media started blindly parroting the line?
It's not in their interest to show any casualties even if they had some. It's as simple as that. Chinese have a significant appetite and national capacity to absorb casualties in order to pursue their interests. They maybe soft, as per many Indian perspectives, on account of not being bloodied recently, but that is perhaps a transient issue.
