Ten

10 (Chinese Character: "十")

The middle finger crosses an extended index finger, facing the observer. Ten could also be expressed by crossing the two index fingers. 

Or：The fist is closed with the palm facing the signer.

Or: The arms are raised and the index fingers of both hands are crossed in a "T" with the palms facing in opposite directions, often in front of the face of the signer, making the Chinese number 10.

The use of the signs corresponds to the use of numbers in the Chinese language. For instance, the sign for five just as easily means fifty. A two followed by a six, using a single hand only, could mean 260 or 2600 etc. besides twenty-six. These signs also commonly refer to days of the week, starting from Monday, as well as months of the year, whose names in Chinese are enumerations.

Counting with fingers is often different from expressing a specific number with a finger gesture. When counting, the palm can be either facing its owner or the audience, depending on the purpose. Before counting, all fingers are closed. Counting starts by extending the thumb as the first, then the first finger (the index finger) as the second, till all fingers are extended as the fifth. Then counting can be continued by folding fingers with the same sequence, from thumb through the little finger, for counting from the sixth through the tenth. Repeat the same method for counting larger numbers. One can also start counting with all fingers extended. Some believe that for formal scenario such as giving a speech or presentation, counting with the palm facing the audience and starting with all fingers extended is more polite, since the gesture of finger folding represents bowing.
