Don't.
A lot of people here think we have lượng falling out of our pockets and we can lend 20 or 100 triều and never miss it. People I've barely met try to borrow amounts that I wouldn't lend to an employed friend in the USA, and act weird when I won't do it.
Friend of mine is a white NNN like me, wants his GF to get a job ... if her coworkers see she has a foreign BF, it's one loan request after another. He tries not to appear at her interviews or jobs.
We will lend to people with the means to pay back, on some schedule, even if it's extended. But those random requests ... No.
Same friend's GF has a tape loop in her head with one word in punched tape: family. She was always asking for money, large amounts, to give to them, not just P&M but friends of distant cousins for really frivolous reasons. He gives them a monthly stipend of ten mil and even then has to do it in installments or they'll burn through it and want more. Mom has some benign liver tumor and would rather waste money on hospital visits and pain meds (dope) than get it fixed. Never a thank you, and the poor girl gets four or more calls a day demanding more. Family's trained her to feel obligated.
My friend in Saigon gives his GF's family a staggering 30 mil a month, non-negotiable, and he doesn't have a job anymore. This is atop a lavish life going out to eat at fancy places (we go bình dân) and a rental in D1 so he is burning through his savings to the tune of $2500 a month. What he gives her idle family in a month would last most people here a year.
We've had a few people borrow and vanish, that's the pattern. Also had others scrupulously pay back on time, not suggesting the whole country is a scam.
Be very wary about lending.
