what is "TargetName" in CMsgDOTACombatLogEntry mean

[NeverMore614]

I can receive a hero death callback, and I can conclude that "TargetName" and "AttackerName" are both the deceased and the killer, but I cannot determine which hero it is from the "TargetName" and "AttackerName" fields, So where should I get hero information from

This is what I printed out, which seems to be the killing information of sand_king, which is consistent with the statistical information on the website,
