When using chopsticks, first align the tips of the two chopsticks, and gently hold the chopsticks with your thumb, forefinger and middle finger. The thumb is placed next to the fingernail of the index finger, and the chopsticks are fixed between the two fingers. Put the fingernail of the ring finger under the chopsticks, leave a distance of 1 cm behind the chopsticks, and only move the upper side of the chopsticks when using.
