I heard something(long time ago) that Milky Way can be seen in South hemisphere only, is it true? If so, what is the reason?

That is not true. The band of the Milky Way can be seen from any latitude on the planet. It just requires the right time of year and a dark sky.
The band of milky way is inclined by more than $60\deg$ to the celestial equator. Hence, it can be easily seen from the southern hemisphere.
In fact, the milky way center lies in Sagittarius (a southern hemisphere constellation), which means,
The Milky Way would look better in the Southern Hemisphere.
