Today, I had to go to Sacombank. Although it's a Vietnamese bank, I didn't expect its tellers here to speak Vietnamese, but both tellers I dealt with were Vietnamese. There was a large map of Vietnam on a wall.

Done, I went to a huge market built by a Vietnamese, Đào Hương. She's a coffee magnate. I bought a bag from a Chinese lady whose helper, a Lao, spoke bits of Vietnamese. The Vietnamese elementary school here even has Lao students, although lately, more Laos are enrolled in the Chinese elementary school.
