Mahjong

Having memorized the techniques, Di Tou raised his eyes and looked at Li Chang Hu, who similarly raised his head and, with a lift of an eyebrow, asked, "Have you learned the techniques?" 

Hearing this, Di Tou was slightly not assured of himself and said, "I've roughly memorized the contents and at least in principle should be able to perform, but in actuality, without any practice and time to work through the techniques, I'm afraid it's a bit difficult to say that I've learned anything." Pausing for a moment, Di Tou let out a slight chuckle and threw in a degrading comment, "I'm a bit bullheaded, so I'm slow when it comes to picking up new things."
