Large latency despite having servers in Vietnam

I am Vietnamese, using Cloudflare DNS, it is surprising that Cloudflare DNS latency is nearly 2 times higher than Google DNS while Cloudflare DNS has servers in Vietnam (and Google DNS is not yet).
Below is the image when I checked with the ping and tracert commands, both of which resulted is Google DNS lower latency Cloudflare DNS!
Anyone have any solution to reduce latency?
