A very funny joke

Di Renjie: 'There is a car parked in this remote area. Yuanfang, what do you think?' Yuanfang: 'Sir, this car must have something hidden about it.' After hearing this, Di lifted the car's hood and was shocked: 'Wow! Yuanfang, your insight is correct, this car really has an engine! But there is also a deceased person inside the car, Yuanfang, what do you think?' Yuanfang: 'Sir, there must be something suspicious about this person.' Di Renjie: '1, 2, 3, 4... this person really has seven orifices! Yuanfang, you truly are my capable assistant!' Yuanfang: '...' Di Renjie: 'The deceased is also a beautiful lady! Yuanfang, what do you think?' Yuanfang: 'There must be a huge secret on this person.' After hearing this, Di lifted the deceased's clothes and stared in shock, exclaiming: 'In my life, I have never seen such huge breasts! Yuanfang, you really are a remarkable person!!'
