Why don't shepherds wear pants?

It is a traditional custom for shepherds not to wear trousers, due to climate problems, economic reasons and Hindu customs. One is traditional habits. Historically, Nepalese mostly engaged in farming and worked in the fields all the year round, forming the habit of barefoot. Up to now, Nepalese farmers still keep the habit of working barefoot, and only wear straw sandals when entering the city. The second is the climate problem. Nepal has a mild climate. Most areas are not cold in winter and not hot in summer. The annual minimum temperature in Kathmandu is not lower than 2 degrees Celsius above zero. The pleasant climate allows Nepalese people not to worry about keeping warm under their feet, and socks are not a necessity. The third is economic reasons. Not wearing shoes can save money for Nepalese shepherds with low income. In Nepal, slippers and sandals are very cheap goods and can be bought everywhere. Each pair of shoes is only 20-30 rupees, equivalent to three or four yuan. Few manual workers in Nepal wear socks. Fourth, Hindu customs. Nepalese are mostly Hindus and need to go to Hindu temples to worship frequently. When they enter the temple, they must take off their shoes to show their respect for God, and barefoot can show the piety of believers.
