Dr Jiulin Teng
Welcome! I am Dr Jiulin Teng. Over the years, I have developed insights into a number of issues of popular interest. A photography enthusiast, I have also captured photos of places and people that tell stories. This website is dedicated to my thoughts and my photos.

Here are some photos shot in early April 2025 in Tangshan.
Here are a few photos from the center of Tianjin in March 2025.
These photos were taken in Xiong'an in early March 2025, almost entirely in the new city's central park.
These photos from Baoding were taken in early March 2025 around the historic center of the city. The highlight here is the Garden of Lotus Lake.
These are photos that I took in Zhengding during a visit in early March 2025. Most were from the restored fortified walls (also known as ramparts).
This is a collage of photos from Qingdao in the end of February 2025. The weather had been chilly and foggy throughout, which gave the city an interesting, if smoggy, atmosphere.
Despite crafty marketing stories, the Volkswagen Phaeton is objectively worse than the D3 Audi A8 and not a very good car even at launch. Today, I list four hard facts to support this argument.
Today, I go over the three stages of the naturally-aspirated version of the VW-Audi W12 engine; they correspond with three generations of Audi A8s in which a W12 was fitted. I will highlight the unique design elements of the W12 in detail, too.
BMW is thought by many to have stronger diesel than petrol engines. This is in fact a new phenomenon. Today, I go over the evolution of 5 BMW inline-6 diesels and rank them into three tiers.
Lancia is celebrated for producing some of the most innovative cars in automotive history, blending style, engineering, and racing pedigree. Today, I go over 10 iconic and collectible Lancia road cars.
Today, I go over the construction, performance, reliability, and applications of six Mercedes 6-cylinder diesel engines. I also rank them into three tiers.
Today, I go over the evolution of six Toyota / Lexus V8s over two generations in terms of construction, performance, reliability, and applications. In the end, I rank them into three tiers.
BMW has always made some performant and characterful, if fragile, V8s. Today, I go over the evolution of seven BMW V8s over four generations in terms of construction, performance, reliability, and applications. In the end, I rank them into three tiers.
In this blog, I go over the evolution of eight Mercedes V8s over seven generations in terms of their construction, performance, reliability, and applications. In the end, I will rank them into three tiers.
These photos were taken at the annual autoshow in Tianjin in October 2024.
These are photos taken in the City of Tianjin during the summer months of 2024.
