Chinese language is getting quite popular in Nepal these days as well. There are many schools teaching Chinese these days, so why not Chinese? Let anyone who knows how to speak Chinese or English or Marwari or another language prove their language skills by speaking in the language of their choice in the hosue. It is a "secular" country why restriction on any language? Let them speak the language of their choice. Don't talk about nationalism? Who cares about nationalism or patriotism?? If there are many who do not understand the language being spoken than hire an interpretor to explain it to them. There are many people who go to "Bishwa Bhasa Campus" let them get employed for a change. LOL
