It's not artificially glued, but your strings are not authentic Nepalese donkey kong, but Indian or Indonesian seeds. We can see from two aspects. The first is the white line you mentioned. The gap is very shallow, and each string basically has a white line, which is the most obvious performance of Indonesian seeds. The true Bodhi in donkey kong, Nepal, has a deep gap between petals, and the white alkali-resistant color is completely different from this white line. Second, the hole crosses. From the authentic Kongdaokou in donkey kong, Nepal, you can see the Indonesian Seed or Louhong Kongdaokou at a glance. All you have to do is search for keywords on Baidu and find comparison photos. I attach a Louhong tunnel, and you will know it at a glance. Look at the second one, and then look at the tunnel in donkey kong on the left.
