In Pakistan, after the Independence and the migrations in 1947 the small regional dialects were assimilated. The Haryanvi people who settled in Pakistan slowly switched from Haryanvi dialect to standard Urdu language. Although older generation may still speak Haryanvi.
The Haryanvi people (originally from Haryana) are scattered throughout Pakistan (especially in the Punjab province). The cities of Jhang and Multan have good Haryanvi populations.
People have settled down mainly in the districts of Lahore, Sheikhupura, Bhakkar, Bahawalnagar, Rahim yar Khan District (specially in Khanpur tehsil), Okara, Layyah, Vehari, Sahiwal, Phullarwan District Sargodha and Multan of Punjab.
Fewer people in Haryana know that Haryanvi Muslims living in Pakistan have kept their culture intact so far. we found some interesting videos on youtube.

In 2017, a “Haryanvi mushaira” was organised in Pakistan :
It is rightly said by someone in the comments of one such video that “culture has its own destiny”.
