Commercial flags (China)

Responding to a question and answer on the FOTW-fb page about a mysterious Chinese flag flown over disputed territories, Nozomi Kariyasu identified the logo on the flag as that of the Bank of China.
http://picm.photophoto.cn/014/019/025/0190250029.jpg is the Visual Identity Manual for the Bank of China and the official flag is a dark red (Pantone 201 C) on a white background. If the flag is 80x120 CM, the logo is placed in the middle and has a diameter of 55 CM. While doing a quick Google image search shows only the white/red flag; I am also certain the red/yellow flag color scheme is also used for patriotic displays. I am attaching both versions of the flag.

COSCO company

A flag can be seen in a Yahoo News photo (ephemeral url, but detail seen here) captioned:
"A COSCO company flag and a Chinese national flag fly in front of the company's headquarters in Beijing August 26, 2010. China COSCO Holdings, flagship of the country's premier shipping firm, swung into the black with second-quarter profit on recovering trade, but overcapacity and a possible global slowdown may drag."
It is blue with the corporate logo in white: the word COSCO in a blocky font, the S extended upward into a spike, encircled by a halo.

Dòunán 斗南 Flower flags

Dounan town is close to Kunming, Yunnan's capital. The whole region is famous as China's flower capital. There is a lot of business going on, and I think that purpose of those two flags is mainly commercial.

The success of cut flowers as a new product was due to the initiative of farmers in a village with 1,619 households called Dounan which used to grow vegetables in the suburb of Kunming, the capital of Yunnan Province.
The Dounan Flower Market in suburban Kunming is the largest in China. It opens from four o'clock in the morning till 10 at night. Every day, it receives more than 2,000 flower dealers from all parts of the country. The daily sales reach 1.2 million yuan from the 1.4 million sprays of fresh cut-flower.

Flag Displays

Chinese seem to be crazy for flags, although there are no regional flags. But every shopping mall or company have a own flag in front of their entrance.
Another very popular tradition is to decorate the shop, office, school or sth else with monochrome flags in different colours for any celebrations. Normally, there are blue, red, yellow, green and pink flags together like in this picture.
