After seeing the readings on the manometer of the BP monitor and quickly jotting down the readings, Yang Yu fiddled with the valve and let out the air and took off the cuff off the arm of the person sitting facing to Lin Yu'an at a table in the middle. Yang Yu was very efficient as he took the person's weight and blood sugar, after jotting it down, he sent the book to Lin Yu'an and sat quietly leaving Lin Yu'an to continue on with the rest. Yang Yu was efficient working as Lin Yu'an's assistant nurse and could carry out only such small tasks, although not proficient, but with Lin Yu'an there to guide and correct him, it wasn't hard to get the work done.
