Both cold and hot drafts can cause the needles to drop, so pick a location for your Norfolk Island pine that's far from air intakes, fans, and heating and cooling vents. You should also keep the tree a safe distance from doors and windows that could let in drafts. The root system of the Norfolk Island pine is very fragile and can be easily damaged when the tree is moved. Do not move the tree unless you absolutely have to, and once you find an ideal location where the tree thrives, keep it there as long as possible.  If you do have to move the tree, move it very carefully, and only short distances at a time. Find a location for the tree where it won't accidentally be moved, hit, knocked, or jostled. Repot the plant in spring every three or four years, when the roots become visible above the soil. Prepare the new pot by filling it halfway with your soil, sand, and peat moss mixture. Carefully dig the tree from the soil in its original pot, and place it into the new soil. Fill the pot the rest of the way and cover the root system with soil.  Each time you repot, pick a pot that's one size larger than the current pot. The pot should have good drainage holes in the bottom to allow excess water to escape. While these trees don't like being moved, it is necessary to repot them now and then to provide fresh soil and to accommodate the growing root system.

TL;DR in Vietnamese:
Tránh đặt cây nơi có gió lùa. Tránh di chuyển cây. Thay chậu cho cây cách vài năm một lần.
