During the Tet holiday, a man named Mr. Thuan purchased a large, golden pomelo variety called Ky Da for his altar display, despite its high cost. Originated in Hoa Binh and Tuyen Quang, these oversized pomelos are now grown in various northern regions. Known for their long shelf life and unique appearance, they are a popular choice for Tet worship and display. The selling price ranges from 400,000 to 1,000,000 VND per fruit, with an increase of 10-20% from the previous year due to limited planting caused by epidemic fears. The selection and care of these pomelos are more complex than regular varieties, requiring special attention to stem and leaf freshness, as any loss of these results in the fruit being considered a loss.
