According to Mrs. Ly Thi Huong who is over 70 years old, the only person has kept the secret and produced song than vermicelli. Legend has it that the Nguyen Kings invited An Thai vermicelli makers to come to Hue kingdom to make song than vermicelli but they didn’t succeed because the water of Huong River was different from the Con River’s one (?).

Song than vermicelli is made of green beans. In average, 5 kg bean, after grinded, washed, deposited filtered several times, generates 1.2 kg powder to produce 1kg vermicelli, so the cost is very high, making it not popular.  Nowadays, song than vermicelli making career in An Thai has been remained but the product quality is not the same as before. People in the craft village have tried to improve the product quality, to make eye-catching covering package and to market the product.
