Rai ni beauty.
    What is the common bond between Gurung, Magar, Limbu and Rai as put forward in
     Muluki Ain (National Code of Nepal) of 1854 by Jang Bahadur Rana?

Answer: The four, Gurung, Magar, Limbu and Rai were classified under Namasine(Unslavable) matawalis (liquor drinkers).

"The more prominent of the tribal groups such as the Magar, Gurung, Rai and the Limbu, who lived as agriculturists and soldiers in the army, were accorded the superior rank of the namasine matawali." by Prayag Raj Sharma (The State and Society in Nepal : Historical Foundations and Contemporary Trends) chpt9. Nepal: Hindu-Tribal Interface

    Hence it is better not to mess with these group("yo char matwali jaat sanga kharab na gara") as quoted by J.B Rana. In other word don't masine(enslave) these group or the consequence would
be dire as described by Chandra Prakash Sunuwar.
"The Gurkha one of the fearsome warrior in the world history. In west they are known as  human being without heart. Once upon time they shaken world fighting alongside with the Britain. They are not tall but famous for bravery, courageous and art of warfare in the world .When they draw the khukuri in battle field and run to cut off the enemies head  enemy look at them Like scapegoat{BALIKO TOHOLAYEKO BOKA}. They come and cut off their  enemies head. Khukuri used to be deadly weapon of ancient Kiranti. Still always Kiranti people carry their  khukuri in east. Without khukuri and without Gurkha they were incomplete absence of one. To be complete should be Gurkha and khukuri.There is myth once draw the khukuri and must draw the blood as well in battle field. During the first and second world war khukuri is considered as unexploded bomb and Gurkha not human but something terror force like dark cloud. Once upon time German emperor KAISAR WILLIUM ||{DUTIYA}said that I am ready to let my dear soldier to fight with any army in the world but when I hear  the name of Gurkha soldier I start to tremble from inside the heart. Same thing German president Hitler who shaken world. People think he is reincarnation of Satan had said that if I get Gurkha soldier in my hand without doubt I will destroy the world. General Gillespie who came to attack Nepal later wrote about Gurkha's saying like this RUN THEY WOULD NOT,DIE WITHOUT FEAR,I NEVER SEEN SUCH EXTRA ORDINARY BRAVERY HISTORY OF MY LIFE.

There is statue of Gurkha soldier in front of parliament square in London. Professor Sir Ralph Turner MC. Wrote wonderful word about Gurkha soldier saying like this,
{BRAVEST OF  BRAVE MOST GENEROUS OF THE GENEROUS NEVER HAD COUNTRY MORE FAITHFUL FRIENDS THAN YOU} "

Now this is true beauty of Nepal.
