No where in Vietnam do people hear the word "money" as much as in Sa Pa, a tourist destination in the northern mountainous province of Lao Cai.

The Mong ethnic kids attract the attention of visitors for their innocent and pristine looks. But when tourists take pictures and talk to them, they will show their unsatisfied attitude. Some kids will wave their hands and say: "Do not take pictures, not taking pictures" or "Do not buy souvenirs, do not take pictures" and "No money, not take pictures." The fiercest response of the kids is that they turn away or turn their ass to the lens of visitors.
